Imalent HR20 Rechargeable Headband Flashlight

Up until now, I’ve only reviewed one flashlight bearing the Imalent name. It was the DN11, and although I found it to be very bright and quite unique, others have had issues when operating it in wet weather. I don’t think we’ll have issues like that this time around. This is the Imalent HR20, headband flashlight with internal USB charging, and up to 1000 lumens of searing output!

Light and 18650 battery

A Cree XP-L HI LED is at the root of the HR20.

It’s powered by one, Imalent 3.7v 18650 rechargeable battery (included), or two (disposable) CR123 batteries.

The output of the light is fully customizable from 1 to 1000 lumens, courtesy of an adjustable control ring.

Either the included battery, or an 18650 of your choice, will charge inside the light when the included USB cable is connected to a USB source.

The body is aerospace grade aluminum alloy.

A built-in thermal control monitor will adjust the brightness according to internal and external flashlight temperature.

A fully regulated constant current circuit keeps the output as bright as possible.

In addition to a constant output, three flashing modes are available: strobe, SOS and beacon.

So Simple to Operate

Just give the power button a soft click, and the HR20 comes on. A second click turns it off.

Once on, the output is adjusted by turning the control ring. Within its range of movement, you can adjust the brightness to as low or as high as you want. Movement of the ring is easy, and the tension is neither to too lose or too tight.

To activate the flashing/emergency modes, press and HOLD the power switch, either while the light is on or off. The sequence is strobe>SOS>beacon. To switch from one to the other, press and HOLD the button. To return to the previous (non-flashing) level…continue to “beacon” then press and HOLD a final time. To switch off from any flashing mode, click the power button once.

Imalent HR20 Impressions

The HR20 is a very cool headlamp/EDC hybrid.

Not long ago, I reviewed the Olight H1 Nova, which is a similar headlamp hybrid. Although the Imalent is larger and brighter, it reminds me of the H1’s ability to adapt.

The inclusion of the rotating ring is pure genius! It’s the ultimate in output customization, and allows the user complete control of how much light to emit.

Since it uses an 18650 battery, runtime should be fairly good.

I’m quite pleased with the Imalent HR20 and can’t think of any possible problems that might arise, or see any current issues or concerns.
