I reviewed the Sofirn HS21. This headlamp has a combination of premium features that I’ve never seen together in a headlamp!

General thoughts after a week of usage/size comparison/practicality/interesting things:

  • So it seems like Sofirn releases a new light every time I check their website, and some of them are quite similar. So when I got the HS21 in the mail, I felt pretty indifferent about it. But on closer inspection, I think this has to be the best headlamp they’ve made. Sofirn provided me with a sample of the HS21 for this review. I was not paid to write/record this review. I have not held back on any negative opinions of this light. I think the HS21 represents a turning point where the line between ‘budget’ and ‘premium/mainstream’ lights seems non-existent. The HS21 has separate red, spot, and flood LEDs - all with regulated output on all four channels. The head rotates to change modes, the headband mount has a snap-on system, and there’s a motion sensor that allows hands-free operation of the light. All of these features are only heard of on far more expensive lights, and I think Sofirn has outdone itself this time around! This is a must-have if you’re looking for a headlamp.
  • What’s in the box? HS21 + 18650 cell, headband, USB-C charging cable, instruction manual, and spare o-rings.
  • Comparison with Nextorch Max Star - twice the price, but the HS21 has so many extra features, it’s no contest. Plus, you can replace the battery easily. The only similarity is the rotating head switch.

Overall Construction, LED, lens, bezel, and reflector

  • Great quality machining - especially at this price point. There are no rough spots or imperfections. The design is practical and minimalist. Everything has a function. Anodizing is between matt black and smooth, and slightly grippy. There are some shallow cutouts on the body/head, and the back of the light - this helps the light to stay in place when attached to the headband.
  • Single rubber switch in the center of the battery tube. Also serves as a battery indicator. The head is also made of aluminum and rotates between four pivot points to access various modes. The rotating mechanism feels firm and clicks into place confidently. On the right side of the light, there is a USB-C charging port with an LED charging indicator. The IR light or motion detector is next to the charging port.
  • Sofirn has used the same snap-on design headband as with the HS42. This is the best attachment system for headlamps in my opinion as it allows easy installation and removal for those who want to use the headlamp as an EDC light. The light swivels up to 180 degrees. There is also a band running across the head to keep the light extra secure. I find that’s more necessary for 18650/21700 lights due to the added weight.
  • Under the bezel there is a custom TIR lens that houses 10 different LEDs. 1xSFT40 (6000-6500K), 6xCSP1919 5000K 95CRI LEDs, 3xHFL1-R 620nm red LEDs. The light comes with a buck driver and has regulated output on all channels. That’s something you don’t see on many budget lights.

User Interface:

  • Single click - on/off. Press and hold for ML from off. Double-click to lock/unlock. Triple-click to enable/disable infrared sensors. Rotate the head to switch modes.
  • From on, press and hold for LMHT on all modes.
  • IR sensors - wave RHS to change modes. Hold for 3 seconds for off.
  • Double-click on the red mode for red flashing mode.

Performance - total output, beam profile, longevity, practicality

Considerations

  • No glass lens on the front of the TIR lens
  • Rubber button design - wished they also would use a larger one. Metal.
  • Proximity sensor/IR sensor can be sensitive to ambient light, and nearby objects. If you’re using the light in a cave or close to a nearby object, I’d suggest turning off the sensor (triple click).
  • Although you can use this as an EDC light, it doesn’t come with a clip and is a little awkward to hold. No lanyard hole.

Verdict

  • This is hands down the best value headlamp out there right now. If I could only get one headlamp, this would be the one. It has features that you normally only see in more expensive lights. Lots of value given the price tag. Regulated output is important for me in a headlamp, as well as a powerful red mode for preserving night vision. The rotating switch makes it easy to switch between modes, especially when you’re wearing gloves, and the motion sensor is a great option if you don’t want to be fumbling around for the ‘on’ switch.

It is a very featured headlight. I’m happy they didn’t opt for a 21700 battery! I think it is a little big as it is and a 14500 could have been great considering the extended runtime at a good output.

Yeah, it’s already a bit heavy with the 18650 but I like this form factor as 14500 doesn’t offer enough power or runtime for a serious trip.

Thanka for the review.

Ordered one already, and shipped out yesterday. Got a really good deal on it, so Im happy.

Some comments here may be helpful in figuring out this light. I like it, but… there may be a few things that could be improved :slight_smile:

Holy moly, thats some good reading lol. Its impressive how some of you folks are so knowledgeable. Wish I had paid more attention in school.

I really like your dual rotary knob concept. That would be a nice improvement. Theres always room for improvements in everything. But at the same time, needs to be affordable and profitable. Afterall, its all business. Thanks for link user, Im even more excited to receive the HS21. :slight_smile:

Has anyone taken one apart yet? Would be nice to swap the 6500K spot to the 3000K.

Oh good grief, of course after I bought one…

Brilliant Idea! :beers:

But you don’t want to keep it, eh? :slight_smile:

I am also really glad Sofirn chose 18650. It’s still rather heavy for 1x18650, but it’s bearable on head :grin:
And I am very glad for regulated driver :+1: :+1:
Generally it’s a great headlamp, just wish it was lighter - but that’s the price for all the gimmicks.

The sensing range is no different to my Wuben E7 & Urflamp C6 though. It has to be a brightly lit room for the sensor to act up. During the day with the sun shining through the windows it causes the sensor to malfunction, but not at night with just the room lights.

These are starting to snap from the high tensile stress, I have two snapped brackets. This is a dedicated headlamp so no real need to attach/detach regularly. For the HS42 it’s nice though, but I really do hate that it requires both hands to adjust the angle. The Wurkkos HD20 & Sofirn HS20 headbands are better suited for easy adjustment with one hand, especially out hunting or farm use. For city folk I understand you just set it and you’re fine.
