The Best CREE LED Comparison

Shopping for a new flashlight can often be confusing. But what about trying to make sense out of understanding what type of LED the light is equipped with? This is where the best CREE LED comparison can help.

Forget ‘Grease’ – CREE Is The Word!

CREE, Incorporated was founded in 1987 at North Carolina State University. The research that went into the development of cheaper and more efficient ways of producing light, have almost become a household word! For those interested in handheld flashlights, the CREE LED has become the dominant force responsible for bringing the devices into the 21st century!

When You’ve Seen One, Have You Seen Them All?

With regards to some things, yes. With regards to LED’s, no. Some will say that LED’s have become smaller over the years. Some will disagree by adding that it’s the “die size” that has increased. LED’s vary in size. These differences, when coupled with the size and shape of the reflector, are what give YOU the user, the beam that you prefer.

Read on to discover how to determine this when shopping for an LED flashlight.

Alphabet Soup

All this wonderful technology has created quite a  challenge for consumers. It’s not enough for flashlight seekers that they must understand terminologies that relate to lumens, battery types, run times etc… but trying to make sense of the LED models themselves can be quite mind boggling!


This is a CREE XP-G R5 LED


Here a basic roll call of the XLamp LED models that CREE has introduced over the last decade or so.

Basically in order of consumer appearance, are XR-E, XP-E, XP-G, XM-L. These are the LED models, so to speak. Each model however has several luminous flux bins. Please don’t ask me to define that terminology, just know that it exists and it’s one of the components that you should have a basic understand of when looking at flashlight specifications.


Flux Bins Rule!

If you read the paragraph above, then you’re already familiar with what flux bins are. If you didn’t…scroll up and read it before continuing.

The flux bins are (more-or-less) brightness codes…in the form of a rating.

There’s no denying that flashlights have become brighter over the years. And although the reasoning behind the naming of the codes means nothing to consumers, just try to remember that with each sequence of codes, the lights have added more lumens!

An example of the flux bin codes that have accompanied the LED models (as noted earlier in the article) have had naming references such as Q2, Q5, R2, L2, U2, T6, etc. These codes always follow the model number. Over the period, there have been many combinations of bins assigned which have not become flashlight components. Below, are the combinations which you are more likely to see, or have seen.

Dissecting The Bins

  • XR-E (R2)

A light with this LED (if there’s still one in the clearance closet) will be several years old. Its highest lumen count will be around 300, using lithium batteries. It WILL however have excellent throw! (enabling the beam to travel at a great distance)

  • XP-E (R2)

Not much different than XR-E except for its size. Performance about equal.

  • XP-C (Q4)

If you should see a flashlight with this LED…pass on it. The XP-C is a low-power LED which offers a much lower maximum drive current than others in the XP family. It’s also much cheaper to produce. It won’t offer a lot of lumens and is capable of over-heating itself to death (causing permanent failure) due to the cheaper mounting material used in the assembly. On the retail level, flashlights with this LED have been known to be sold at cost-conscious big-box stores. Check labeling carefully!

  • XP-G (R5) and XP-G2

The ‘G’ and ‘G2’ line feature a boost in lumens. The ‘G2’ offers up to 20% more than the ‘G’. This line also offers throwing capability much closer to that of the older XR-E. Note that the size of the ‘G2’ is a tad smaller, producing a slightly smaller beam.

  • XM-L (T6)/(U2)

    CREE XM-L2 T6

    An XM-L2 T6 LED

Virtually all flashlights made today use an XM-L LED. This LED produces a full-flood beam, with less throw than the XP-G.  Total lumen output for the original XM-L peaked at near 700. Differences in the T6 and U2 flux bins include higher brightness. The T6 cannot output more than 910-975 lumens. (*see note) Meanwhile the U2 bin is 7% brighter than the T6. Overall beam distance (throw) has increased since the XM-L. Both of the more recent bins have less flood overall.

Part of what makes the XM-L visually distinctive, is its slightly larger size and a six-line grid across the die.

  • XM-L2 U2/U3

Similar in size (5mm x 5mm) to the XM-L, the L2 has increased brightness by about 20%. It has also omitted the “grid” found on the XM-L.

The T6 bin is present in both the XM-L & XM-L2 emitters. T6 output within the L2, peaks between 1044-1119 lumens.

The U3 bin has now appeared in many flashlights. Brightness has modestly increased again. Top output is 1193-1268.

  • XP-L/HI

Continued advances in LED technology made the XP-L LED available in the spring of 2014.



The XP-L is the same size die as the XM-L2, but it’s placed onto the smaller size board of the older XP-G. Whereas the XP-G is king when it comes to “throwing” capabilities, the XP-L doesn’t throw quite as far, but it makes up for it in brightness and the fact that it can be driven at much higher currents.

About a year after its introduction, a “high intensity” version was released. This is now known as XP-L HI. In some new flashlights, including Manker’s T01, you’ll find the “HI” LED. Their are various versions of it, and the T01’s brother (U11) features a “HI” in V5, which puts its highest available output between 1176 and 1227. The T01 is 900 lumens, the U11 is 1050.

  • XHP35/HI

With 50% higher performance than its nearest predecessor, the XHP35 LED can be found in various types of lighting and has a traditional “domed” shape to it. At 3.45 x 3.45 mm, it’s a tiny LED… BUT can output up to 1883 lumens! One of my favorite flashlights (to date) using an XHP35 is the Olight M2R.

Meanwhile, the “HI” (high intensity) version, although the same size, is FLAT (just like the XP-L HI) and is capable of producing up to 1483 lumens! It produces a very focused beam with a tight center-spot. A good example of this, is the Manker MK41. There’s also another variation to this LED, which is designated as “HD”.

  • XHP50/50.2

The XHP50 is part of CREE’s “Extreme High Power” class of LED’s. Once again, it’s shaped like a dome and at 5×5 mm, it’s a bit larger. It achieves DOUBLE the output of the popular XM-L2, at an impressive 2546 lumens. For an example of  XHP50 power, see the Nitecore SRT9.

For the 50.2, lumen “density” was improved a bit, even though size and shape remained the same. Output also increased a small amount, to 2654 lumens.

  • XHP70/70.2 

    The CREE XHP 70.2

With the XHP70, lumen density was increased…again. This is the largest of the group at 7×7 mm, and still retains the domed shape. Naturally, output was increased…again! This time, it reaches an astounding 4022 lumens!

For the 70.2, we have slight improvements once again. This includes higher lumen density, higher voltage characteristics, reliability and optical performance when compared to the XHP70. For lumens… a ‘small boost’ to 4292 was achieved.

When Tints Were King 

Two tints; neutral white & cool white

LEFT: Neutral White — RIGHT: Cool White

Not so much with today’s XM-L technology, but varying tint bins were all the rage with XP LED’s. Many new variations of popular lights were released with neutral white and some warm white LED bins. Although a popular alternative to the standard cool white LED color, the warmer tint bins featured less lumens due to the thicker LED coatings.

* I always feel it’s useful to know that there are an abundance of cheaply made flashlights in today’s marketplace. The internet is full of them. Many of these lights feature a XM-L T6 LED. And many that do, routinely inflate their lumens to 1600 and above. As noted in the XM-L section, the T6 bin is limited to slightly less than 1000 lumens. The consumer should be aware of these blatant inaccuracies. For more information click this link.

Something else to keep in mind, are the output estimates from CREE. In many flashlights, “out the front” lumens are less that the given output which sometimes gets absorbed by the reflector. Some lights have better designed optics to alleviate lost output. The biggest offenders in “lost lumens” are the “focusing” flashlights, whereby the beam widens and narrows by pushing and pulling the head forward and backward. These are mainly low-cost, poorly-made, generic flashlights.

  1. nice info, im glad to hear there is more efficient ways of producing light. Lots of stuff here I didn’t know about!

  2. Wow, that’s a lot of info! Thanks for sharing it!

  3. very informative, thank you! it would helpful to know what amount of run time we could expect on a given battery. meaning how long the bulb would produce bright light using for instance an 18650 battery. i also noticed that many flashlights use an aluminum reflector. whereas most flashlights use an aluminum vapor coated plastic one. i have to assume this is because of the amount of heat produced by the LED. i also know that Halogen automotive lights use aluminum vapor coated steel or glass (solid glass drop in headlamps), so it seems that the aluminum vapor coating is the standard. do LED’s make so much heat that a vapor coating will not hold up?

    • Thanks for commenting! LED’s DO create a fair amount of heat, and the best flashlights do what they can to minimize (and prevent) any possible damage caused by excessive heat. Your question about runtime is usually answered within the specs of most lights. How long the brightest output is good for depends on many factors…including the battery.
      I wish I could comment more intelligently on the subject of vapor coating. This is (admittedly) something I’ve not heard much about…but thanks for mentioning it, it’s worth looking into!

  4. Thanks for the info. Very valuable.

  5. Thank You very much.

  6. Very useful information. I appreciate you taking the time to write it up. One thing that might be helpful (for others) is if you very clearly state what the brightest lights available today are (for headlamps, etc). From what I could gather from the above info, it’s the XM-L2 U2/U3 (?).

    I also appreciate that you took the time to state that many of the lumen output specs for lights on ebay are bogus (I noticed that, too!). So it helps to know what lighting tech they use to estimate brightness.

    • Thanks for your comment! I’m glad you found the post helpful. Unfortunately it’s the type that needs tweaking now and again, since the technology doesn’t stand still for long! I can’t say that the brightest LED’s today are XM-L2’s etc… In recent months, XP-L (and its various “bin” types) have generally surpassed them. Then, I’ve seen several recent lights with XHP LED’s! Some as XHP-35 and some, XHP-50. The outputs on THESE lights, are way surpassing anything with an XM-L2.

      I’ll try to keep this post as up to date as possible, but sometimes these changes occur without much fanfare. So until new lights are suddenly introduced with the new technology, then it’s not easy to know it has happened.

  7. Thank you for the great write up.
    Can you post an update for the brightest LED available now?


  8. Chauntelle Russell

    I’m looking to buy the brightest, longevity, best quality single lamp white/blue light headlight headlamp. I use a LEDSLENSER white light now but they don’t make the white/blue ones. Could u recommend one or a few that I could check into please? Thank you.

    • Okay, so if I understand the question, you’re trying to find a headlamp that has white and blue beams? I have reviewed a few headlamps, but I’ve never seen one that has multicolored beams. Only seen flashlights with that feature.
      Have you seen the latest Olight headlamp review? If not, here’s the YouTube link;

  9. Are these same LED’s being used now in automobile headlamps and household light bulbs, or are there completely different types being used in these applications? For example, I have recently seen a CREE XHP 50 that was normally meant for automobile headlamps advertised as being used in Nebo’s Redline Blast at1400 lumens. I’d imagine that being driven at a lower voltage than the 12 volts seen in autos makes a difference.

    Someday, can you please discuss the new COB (chips on board) LED’s that are becoming more and more common. PS: I really enjoyed your article

  10. Great write up. I have a torch with a Cree j-a5 emitter. Could you recommend a suitable upgrade please. Cheers

  11. Dear Sir, can you tell us witch is the brightest LED right now in cool white used for flashlight? For example if I want a flashlight Convoy C8 what emitter LED is latest one used and brightest that offer most powerful cool white light? there I have seen the U3, HI V2-1A, Hi V3-1A and I have seen the XP-l V5 with out the HI….I don’t understand why the HI disappear from its model.

    • Hello Dan, Models of lights will change now and again, and with those changes they’ll sometimes configure it with different LED types. I believe the Convoy C8 is one of those that’s gone through different life-cycles, and is available in different versions.

      From what I know at this moment, the brightest type of LED is the “XHP”. I have a few lights featuring it. It comes in a few variations; XHP35, 50 and 70. In the 35 there’s a “HI” (high intensity) and an “HD” (high density). The maximum output increases with each bin variation, with the XHP70 being the brightest…at just over 4000 lumens!

      Thank you, and I hope that answers your question.

  12. Your article mentioned that the LED Lumens is 1000, so if a flashlight only contains one die/led node, then are you saying there is no way it can produce more than 1000 lumens? How many LED dies/nodes (yellow squares for others to understand) would be needed for a 2000, 5000, 10000 lumen flashlight?

    • Thanks for the question Gina!

      A newer type of LED, the XHP, is capable of over 3000 lumens and is currently found in several high-output flashlights. There are also other lights which utilize several LED’s of less intensity, to produce high output. One such light that I reviewed was the Manker MK34, which uses 12 (less intense) XP-G3 LED’s, to total an output of 8000 lumens!

      So, depending on the TYPE of LED… high outputs are possible, even with just ONE LED.

      Thanks for stopping by 🙂

  13. REally great article. I hope you can find the time to keep it up to date.

  14. Great article. I will be using this as a reference point when buying my next headlamp. I’m in the market for a new one, as my last ones (Nitecore HC30 and HC60) were both stolen. I loved the beams on both those lights, but am now curious if anyone makes a better one, as I bought those ones well over a year or so ago. Any thoughts or manufacturers I should look at?

  15. Hi, from a SCUBA diving perspective, would an xhp70 equipped single LED torch work better than say one with multiple T6/U2 LEDs. Is there anything to suggest that the XHP70 are more for focus whereas a setup with multiple T6 LEDs would give a scatter/dispersion effect? Underwater, I would normally wish for a strong beam neither too wide nor too focused and with low back-scatter.

    I know, a rather specific need. That said, lovely informative piece. Any clarity I have now on the subject is thanks to reading this piece.

    • Thanks very much for the comment 🙂

      While I’m not a scuba diver, I would assume that a more general type of beam would be more useful underwater, than say an XP-L HI, with its more focused beam. From what I’ve seen of the XHP-70, it didn’t strike me as having a particularly focused pattern. If you want a more “balanced” beam, then I think most any of them, except those with the “HI” designation, would be suitable.
      Ironically, I’m being sent a diving light for review, which uses an XM-L2(U4) neutral white LED. As I said, I don’t dive, so I might be at a slight disadvantage!

      Hopefully I was of some help with my response. Thanks!

  16. Do they have colored light other than white now or in the near future?

  17. Mr. Wilkie : this is a fascinating article and I have had to read it multiple times in order to get even the remotest idea of how the various incarnations of the emitters affect the overall light produced. In researching what I want, a tactical flashlight, I see that the higher end products have Cool White as the only option, (Thrunite excepted) and in one video I saw, the reviewer stated that the slightly smaller size of the emitter would produce a more focused beam. As of this writing I seem to be between the Thrunite TC12 V2 and the Klarus XT11S. The Klarus has the brighter XHP- 35 while the Thrunite has the XP-L V6 which is slightly larger. But in looking at video reviews of both lights, both lights seem to be pretty concentrated in focus so there isn’t much spill to illuminate the surrounding area 15-20 around you unless you point the light to the ground. I found a light from Brightex Labs, XR1100 that has a feature which you do not like, that being zoomable in order to give more of a flood look. So the questions I have are : 1) does the smaller size emitter produce a narrower beam? 2) Why is the zoom feature a negative? 3) the Thrunite gives the option of either a CW vs. NW emitter color. I’ve read that the cool white is harder on the eyes to see but it is brighter than NW at the same output. True not true? What is your perspective? 4) does having a higher mAh in the same size battery, say a 16850 have any impact on run time, output brightness? Both? Thanks.

    • Thanks for the comment Norbert!

      Your two choices are pretty good! I must correct you though, it’s the XT11GT which has the XHP35, and 2000 lumens. The original XT11S, still has the XP-L V3 LED. As far as those two choices are concerned, the differences in output, 1100 lumens vs. 2000, is negligible. The beam patterns will be slightly different, but not the brightness. PERCEPTION of brightness might be noticeable due to the more focused beam of the XP-L.

      So, to answer your questions.

      Emitter size does not necessarily dictate beam with. One thing that often DOES aid in focusing a beam, is a deep reflector. On lights where the LED is placed within a shallow reflector, the beam is much “floodier”. One characteristic of the XP-L HI, is a narrower, more focused beam pattern.

      For some, having a focusing beam might be an asset. Perhaps this is more personal opinion. I personally don’t like them, because I feel they’re more of a gimmick. The give the PERCEPTION of brighter light when focused. But in reality, the light is no brighter, and in fact, light is LOST in most cases, because most focusing lights don’t HAVE a reflector, so the light produced by the LED is in fact not even being projected out the front! Focusing lights were made famous by Maglite, and mainly appeal to past users of that brand. The light produced by a quality fixed-beam flashlight, with an equally high-quality reflector, does a far superior job at both close up, AND distant illumination, than a focusing flashlight can.

      LED tints are a personal matter. Many “flashaholics” prefer NW or even warm-white, because they allow for better color rendition. For instance GREEN objects (like trees etc) look more natural under a warmer tint. I’m not sure if CW is harder on the eyes. Personally, I haven’t noticed that. What HAS been said to be more tiring on eyes, is the “bluish” tint that many ultra-cheap flashlights produce…all the while claiming it’s cool-white! What is also true, is that CW & NW LED’s are often lower in lumens than their CW counterparts. Appreciators of these tints gladly accept a slightly lower output.

      Finally, with regards to mAh. Yes…higher mAh is like having a bigger gas tank! A larger capacity battery means longer run time, but also longer charge times as well. As I’ve said though, beware of cheap batteries, which artificially inflate their capacity just to increase sales!
      Having more mAh does NOT affect output though. A 1000 lumen light offers the same output whether it’s powered by a 1000 mAh battery, or a 3500 mAh battery.

      Thanks for the questions! Hope the answers have been helpful 🙂

  18. Hi,
    I just ordered a torch with CREE L2 bulb !? I wish i’d read this earlier.
    If you have time, can you tell me where the Cree L2 sits in the grand scheme of things please ?
    Thank for a great great info page.

    • Hi, and thanks for the question. But you need to be more specific on what type of “L2” LED you’re referring to. “L2” is only PART of its name. If you have packaging or a manual on the light, please respond with its full name as given by the manufacturer.

  19. This post was very useful for a novice like me. wish i had read this early. Thanks for sharing and implanting some knowledge to us.

  20. Being a relative novice and basically an amateur in the field of flashlights, I must admit that your article is very helpful and informative and I thank you for that. One thing, however, I cannot understand: how a flashlight that produces a very bright light can have a shorter range, and a device with weaker brightness can throw further. I just do not get the brightness vs. throw relationship. Other than that, kudos to you, BR Winkle, for a great flashlight website!

    • Thank you Tom!

      The differences in throw are attributed to a couple of factors. The reflector shapes the beam. Smooth reflectors produce longer throw. It also depends on how deep the LED is set within the reflector. A “deep” LED always produces a tightly focused beam with throwing distances up to several hundred meters. Those that are coated in orange peel, have shorter throw and greater flood. The output of the light really doesn’t play much part in the equation.

      I hope that explains it a little bit better.

  21. Well, what CAN I say!? This has simply got to be my GOTO from now on in for ANY questions I have about LED TORCHES!

    I am not stupid (My doctor is ALWAYS saying that, but he DOES mutter a lot?) And have been an Electrical Engineer for some 40 Years after studying my trade in the Royal Navy (UK Branch!)But this site is truly a Knowledge font! And YOU Sir are the MAN. Thank You!! And LONG may this site be up and running!

    Just thought, it MUST cost a few bob to keep the site up and running?? So HOW does one contribute?? Wont be a lot (Pension NEVER does go that Far!) but I DO like to pay my way and give credence to someone or thing that deserves it!


    • Hi Chris,

      I appreciate the comment/compliment!

      Yes, it does cost more than a few pennies to keep the site up and running, which I try to offset by linking to Amazon and other merchants. I have never requested contributions from my visitors and have no specific plans to do so. Having said that though, it would certainly be appreciated. For reference, my PayPal address is Again, this isn’t a request for a donation, but if you feel my content is deserving, then I would be most humbled.


      Thanks for visiting 🙂

  22. Very informative article! Thank you for the education. Do you know if Cree will be releasing any new LEDs in the near future? I’ve owned a few Nitecores for about 3 years now and have loved them! It all probably stemmed from back when I was a child in a religious retreat in the woods with the school. My mom had bought me a hefty maglite and I had the brightest light in the whole camp (which later got confiscated by a grumpy teacher with no sense of fun). Would be hillarious if I somehow had a P12GT from the future. People wouldn’t believe it.

    • Hi Andy,

      Keeping up with Cree is harder than with the Kardashians! Yes, new LED types (and bins) do appear from time to time, and keeping track of them can sometimes be a bit of a challenge.

      One of the easiest ways though, is to keep your eyes peeled for new flashlights. They’re usually the first products to feature the latest consumer-grade LED’s.

  23. Hello
    Just find out about that great article! Many thanks for putting all of those very valuable information all together. I am a novice and was looking at the Imalent MS12 after looking at their R90C. I am a little puzled as Imalent said they used cree XHP70 first gen in their MS12, claiming that second gen does not cope well with heat of the MS12, and saying that 1st gen is better in that regard. I have some problem with that statement. Do you buy into this? Do you think this is true? Or did they simply want to cut cost on the MS12?
    Many thanks for your precious opinion on that for the novice I am…

    • Thanks for the question Phil. I wasn’t aware of any of this, but I wouldn’t imagine there’s too much difference between the 1st and 2nd generation LED. Personally, it wouldn’t bother me which one they used because the XHP70 is so robust!

      It might surely be something to look into a little further though.


  24. I have ordered a xpe2-grn-nct with a qlite driver to be installed in a convoy c8 for hunting. I want to build another for general purposes, I use 18650 batts what cree and driver would you recommend?
    Very informative article.
    Thank you Larry

    • Hi Larry,

      Thanks for visiting! I actually have not yet built my own flashlight! But…when I’m ready to, I would certainly consider an XHP LED. Perhaps a 35 or 50. As for drivers, the GXB boost driver (20/17) has seen good popularity. As I’m not quite as familiar with drivers as I am LED’s, that would be my basic recommendation.

      Good luck!

  25. You are an asset to the flashlight community.
    Best regards

  26. COOOOOLLL!!!
    Sorry to be French.
    I do not speak English well.
    I use google trad ^^
    So I make small sentences.
    I notice that on Aliexpress he sells lamps with 2 XML LED T6 but I think that is wrong … Little power …
    I just bought a Nitecore TM06S
    I hope it’s really 4000 Lumens.
    I think so.
    4 LED XM-L2 U3
    1h of autonomy in 4000 Lumens mode with four 18650 of 3400mAh.
    What do you think ?

    Thanking you.

    • Thanks for the comment!

      I don’t own that particular Nitecore, but I think you can safely assume the output to be very close to what they advertise it to be 🙂
      Four 18650 batteries are capable of providing a LOT of voltage to a power hungry flashlight!


    nice layout without all the bling bling, buy me, over here BS. Informative article. The best internet read today.
    Thank you.

  28. I have a soonfire NS17 and its very bright but i think the led is a cree xm l2 u3 led so why is it only rated at 1000 lumens?I was thinking it should be higher.And i noticed some lights ansi rated at 1200 lumens have only 10.000cd but my NS17 has 13500cd.So confusing!And i think i may get a wuben which has a osram p9 led of which i no nothing about.Any help would be great. thanks

    • Hi Robert,

      Yes, flashlight performance claims ARE confusing. To be honest, I don’t pay any attention to candlepower ratings, and I’ve never equated them to lumen output. 1000 is a pretty good estimate for the Soonfire. Even if its true output is closer to 1100, you won’t be able to see the difference. If you want to do the math, 1cd is equal to 12.57 lumens.

      Osram is another manufacturer…like CREE, and they have a line of LED’s, which apparently is finding its way into handheld lighting products. I’m about as unfamiliar with them as you are, since I haven’t been offered any to test and review…yet. I’m sure in time we’ll get our chance.

      Thanks for the comment 🙂

  29. Nice review, mind putting up a timeline or ca. year the bins were released?

  30. Hi!

    Awesome guide! It’s a bit confusing with all the different model numbers and the specifications and this really helps.

    Do you know how likely it is that the different flashlights/headlamps that is sold on Aliexpress/Wish etc really have the LEDS’s that they claim to have? The reason i’m asking is because i got myself a flashlight called Boruit BC10 which claims to have a XHP70.2 LED and that thing is really impressive but it also cost me about 40-50 dollars a year ago.

    Now i’m looking for a headlamp with the same specs (same LED?) and there are _a lot_ of them out there from different brands/specs and the prices just seems to be too good to be true. I mean, $20-30 dollars for a headlamp with 3×1850 batteries and a XHP70.2 LED, is is really possible?

    What’s your thoughts on this? What headlamp/configuration would you go for in terms of maximum light output? IS XHP70.2 the right one to look for?

    Again, thanks for a great site! 🙂

    • Hello Emil!

      Thanks for your comment.

      I don’t own one of those Boruit lights, but I DO see that a couple of versions exist. There’s a version on Amazon that’s less than $50 but uses an XP-L2 LED. There’s a $70+ version which has an XHP70 LED. This makes we wonder which one you have, and it also answers your question, that some of those sites absolutely DO sell products which have been known to “fib” regarding some of their parts. However they aren’t usually within the price range you paid.

      With headlamps, I would stick with those that don’t appear to be stretching the limits of truthfulness. I’ve seen some of those that claim 10,000 lumens and more, and although I haven’t tested any, I’m very skeptical. I don’t believe an XHP70 is practical in a headlamp due to the heat it will produce. If they accept 3 – 18650’s, can you imagine how HEAVY that would be on your head??? No way!!!
      Again, my advice is to stay with known brands such as Olight and Nitecore, which have moderate 1000 lumen outputs, and won’t match the size or weight of your OWN HEAD!

      As always….buyer beware 🙂

  31. Have they released xhp90 Cree chips because I seen torches with xhp90 and xhp 90.2 written on them ?
    Also there are no review of the chip ?

    • Hi there!

      I would be leery of that. There is NO REFERENCE on the Cree website to XHP90 LED’s. Cree currently doesn’t offer anything above 70.2
      Buyer beware! If you get something like that, just know that it’s probably not what is claimed.

  32. Nice article/education!

    I was wondering if you have dived into building our own light yet ?

    I’ve looked into it some myself. Looking to build something with COB or the xhp70(multiple). I live on a farm and with coyotes and mysterious nocturnal flying animals I’m looking for something very bright, big flood and long throw; size, heatsink/cooling and cost not a factor.

    Any recommendations on equipment or direction of tutorial you could steer me to ? So many arm chair “experts” out there today, it’s hard to trust who really knows what’s up or who is really full of BS.

    • Thanks for the comment Ozzy.

      I actually have NOT built my own light. It’s an interesting thought though. Your wish for lots of flood AND lots of throw would be a challenge I think! If you’re serious about this, I would suggest visiting Candlepowerforums. I’m sure there are members there who’ve built their own lights. It’s certainly worth a try!

      Good luck to you.

  33. Would you explain the difference bbetween tthe 18650 and the26650?

    • Hi Rich!

      The difference is size… and capacity. A 18650 is 18mm x 65mm. The 26650 is the same length…65mm, but is 26mm in diameter. Capacities can be higher on a 26650 because there’s more area with which to store energy.

      Hope that explains it. Thanks for the question.

  34. Such a great article. Can you talk more about the Q2 and Q5? What are the rated lumens for these? What rank do they fall in?

    As a side note, I purchased an XPH70 headlamp. That sucker is big but it puts out great light. It’s about 1/2 a pound. It’s not undoable :)!

    • Hi,

      So glad you enjoyed the article. Unfortunately there’s not much to elaborate on regarding those older LED’s. Lumen limits will be within the 200-300 range, and their ranking is definitely on the lower end as well. With almost any technology, you’ll always find a few fans…no matter how scant they will be. Those who bought their first flashlights equipped with them, might still appreciate the yellow-ish tint and/or beam profile…simply for what it was, at a time when the industry was in its infancy.

  35. I have not been able to put this article/review down it’s great! Thank you. Would you happen to have an update covering and even if possible giving your opinion on the Cree XHP 90 please?
    I find LED’s literally infectious am I alone?

    • Thank you Adam!

      I will check again…but the last time looked, I saw no evidence that CREE has yet to produce an XHP-90 lamp!
      And yes LED’s can become quite infectious!

  36. thank you for your article about xml & xhp… i got one question… what kind of led suitable for flashlight (not big). and that flashlight can easily put in your pocket? and can use anytime… because some very bright led (exemple xhp70) using too much power & drain your battery quickly..

  37. Heat sink paste applied in the right places knocks down the rise in temp and on some LED’s enabled to increase voltage. I own a led flashlight, modified to run on 16340’s and it runs on 2x 16340 = around 7.4V DC in place of 1x 18650 3.7v and is a real tight focus as in you can ID a crouched down person or animal @200+ yds, and it gets really hot fast. It is a weapon if trouble is in your way, It’s blinding!

  38. great article , but i think u turn on torch and zoom in you can also see different shapes of different LED

  39. Hello, BR Wilkie,
    Thank you for all the good info. I somehow thought that Cree started as a UNC-Chapel Hill project, located in Research Triangle Park (RTP).
    Given the RTP welcome to H-1B engineers, I’d like to know whether Cree is a magnet for non-citizen EEs, and how that affects the job market for citizen EEs. They are more expensive employees than alien residents, who are “cheap, compliant, and caught,” that is, kept from changing jobs by H-1B commitments (or debts of indenture) to one’s “sponsoring” employer.

    My good flashlight is a baton with 5 EBL 26650’s and 24 Cree LEDs, for 20K+ lumens in a focused beam. Is there a newer, focused LED mirror that presents a pencil-thin beam which is invisible off axis? That is, a beam which is nearly inaccessible to surveillance by those for whom it is not intended?

    Is there an Optics-defined limit to LED miniaturization and concentration, and are Cree and Osram approaching limits specified by physics? Is there a benefits-costs curve that goes vertical at some voltage or lumens limit that can be calculated by physics or optics or electro-magnetism? Is there a predicted point of dimishing returns where increasing lumen yield fails to offset the increasing cost of more powerful chips? Do the advances in LED technology have any ramifications in or transference to the fields of electricity transmission and magnetism technology, such as MagLev? And how does one monitor the sales, expenses, and profits of Cree (and Osram) in order to make informed stock investments?

    If I am talking you to death or asking questions of little value, just say “STOP!”

    • I believe your questions should be asked directly to a species of extreme intelligence! — OR perhaps to someone who is FAR more of an LED “geek” than I proclaim to be!
      Appreciate the comments though!

  40. A very helpful article.
    I hope you update as new LEDs are released.

    A little more in depth info on the bins would be most welcome too.

  41. Hi – I have owned the Eagletac D25C torch for over 5 years and use it as an EDC light. I have yet to experience any problems with it, but I am tempted by the newer 800 lumen version. It comes with 2 options — an xm-l2 U4 and an xp-l HL. I read you very fine article and I understand that several differences in design affect/effect throw, but given the same reflector in the same light, which of these two LEDs will provide the longest throw? Thank you for considering this question.

    • Hello Don,
      Eagletac does not seem to be too upfront, with providing specs on the alternate versions of the light. BUT in my experience, I would venture to say that the XP-L HI would have longer beam distance. It would seem that regardless of which LED it has, having good throw is one of its main features.

      Good luck on your decision!

  42. Are the increases in lumens between the different leds due to increased efficiency, or just the ability to handle more power? For example, is a newer 2000 lumen light using twice the power of an older 1000 lumen light?

    • Thanks for the question David.

      I believe to an extent, yes. Most flashlights today are much brighter, AND more efficient than they were a decade or more ago. Whereas MORE LED’s in a light, three, instead of one, for example, will draw more voltage from a battery, a 1000 lumen light made this year, will have longer run time, than a 500 lumen light did from 15 years ago.

  43. Glad I was able to stumble here in your article about LED lights. Will surely share this with my friends.
