This little flashlight has me hooked! It's a Sofirn SC21, and if you keep reading…
Working in conjunction with Budget Light Forum, the Sofirn SP36, is an incredibly bright, user-defined flashlight which features NarsilM, V1.2 firmware, which can be configured to the user’s personal preferences. How does that work you might ask? Read on!
I didn’t include the box in the photo, since it’s just plain, brown, and has no printed markings. But as you can see, the accessories include the manual, some o-rings, and a USB charging cable.
When you first turn the Sofirn SP36 on, the default ramping UI is what you get. But depending on either how curious, or adventurous you are, you might want to switch over to “mode set” and check out the offerings.
Ramping mode couldn’t be easier to navigate. Just press and hold the switch, and watch the output get brighter and/or dimmer. It’ll do a slight blink when it reaches turbo, and if you leave it on that level for more than a minute, you’ll notice it starting to get very warm. By default, a timed step-down is set at three minutes. But… you can change that, or disable it completely!!
Ramping allows you to change the direction of the ramp at will….unless you pause (after release the button) for more than 1.2 seconds. Pausing will cause the ramp to continue in the same direction.
Within each operating interface, are the emergency modes, and a couple of other neat little tricks. Here’s a rundown of what’s available.
*From Strobe, the other three flashing modes (bike flash, SOS and beacon) can be reached, but in order to get them, you need to double-click (without pausing) from Strobe. Once you’re locked-in to one of them, a short HOLDING press, will go in REVERSE to the previous one. Strobe can be enabled or disabled at any time. Strobe can also be enabled separately, WITHOUT the other “blinking” modes.

It’s used for everything, and illuminates in RED when the USB cable is connected. It turns GREEN when the charge is complete.
The illuminating switch is used together with the LED’s to blink out battery voltage etc. It also remains ON each time the light is turned off. It can be switched off (until the next time it’s turned on) the same way it can on other lights, by performing a quick HOLDING press, followed a quick click. OR — it can be completely disabled (which is what I did on mine). To see how, follow the “manual” link (noted above) and look for “indicator LED enable” for instructions on how to disable it.
Please note that it was set to “ramping” and the captured images are an approximation of what “low” and “medium” would represent. Obviously “turbo” needs no estimate.
With the NarsilM firmware, the SP36 can do just about anything desired by the user.
Ramping is the simplest way to use the light. And even on THAT setting, you have instant access to moonlight, turbo, and strobe.
For those who like a more “precise” output, and want up to SEVEN pre-defined increments of light, then “mode-set” is for them. Here are just a few of the attributes that the SP36 allows the user to customize;
The SP36 is a solid, hefty flashlight. It’s not terribly big, but it’s reasonably heavy. It’s too bad it doesn’t come with a holster, since there aren’t any obviously easy ways of carrying it.
There are enough settings, and enough ways to personalize this flashlight, to please even the most discriminating flashaholic.
Your opportunity to own a Sofirn SP36, is just a click away. This link will take you to the SP36 page at Gearbest! If you’d prefer to shop Amazon Prime, click here!

The switch button is on a lockout. Cannot turn it on for the green light indicator after clicking 4x, hence the flashlight is not usable. The button turns green if the power cord is connected to the power source, the flashlight is then usable for the different modes.
Please advise a solution to the above-stated problem.
Thank you for your prompt attention.

Hi Fernando,
Sorry you're having a problem!
Please confirm, do you have it set to RAMPING when you're clicking 4 times to unlock it?? Is there a chance it might've been changed to the MODE interface? If so, unlocking it is a different procedure; To engage “lock-out”, (from OFF) click TWICE quickly, then perform a HOLDING press. Repeat to unlock.
Let me know if that works.
