Armytek’s headband with the plastic holder is my favorite for right-angle lights, and I’ve tried a number of them, including the fancy-looking one from Olight. I find it the most comfortable, and it allows installation without removing the pocket clip, though that doesn’t appear to be intended.

Hmm, the headband seems to be the same one being sold on Convoy’s AliExpress store, so tapping the same supplier for this headlamp logistically makes sense. …But aesthetically, it sure detracts from the light, haha. Maybe Convoy-branded headbands could be made down the road, similar to how Simon’s selling Convoy-branded holsters.

Headband groupbuy?

Is the Armytec hea strap the best one right now?


For me Armytek have the best holder and Zebralight and Acebeam the best headband. Few months ago Armytek has changed the headband witth another of more bad quality, similar to Boruit headband…

The strange thing is if you google HB02 you find different versions.
I got a pair of these and i’m very happy with it.

just for fun,i dont know if BLFers need this Big Smile



Could you please put this lens on sale? I think, it would be super useful for cases, when LED has unusual light emitting surface.

E.g: think about this quad emitter array – or just when first generation XHP50 or 70 is used Smile

One more question: do you have a reflector, which can fit this quad emitter array above? Or at least, is it possible to drill a d = 11mm hole into a C8 reflector?

i thought no one was interested in this stuff
and maybe diffuser is more useful

is there a hole in the spot if you a SMO reflector on quad emetter array?

The H1 is back on GearBest now at $30USD… but with that emitter, UI, and band, nah.

Probably any 17mm driver that also fits in the S2 (Simon mentioned that already). My preference still is Biscotti or plain single mode. You can buy a host, driver and LED and assemble it yourself – quite easily.

“Mode: 2 (LED; SOS) “ Big Smile

To be activated when you want to say “help me why did I buy a headlamp with strobe in the main rotation” Silly

100% honesty though, I really like the look of the lamp, and I want to like it but I just…I just can’t. Not yet.

Won’t it be more convenient to use short click to turn it on and off and long press for switching modes?


Ooooh yes!
  • single press is on/off
  • long press from off is moonlight
  • double press from anywhere is turbo
  • long press while on changes low/medium/high

Thanks ,good suggestion, but i have to change it in next batch now ,

When can we order this second batch?? the actual UI is a nogo for me, Sorry….
my wishes: UI as described, usefull Headband and HiCRI SST20 LED

Boaz sells sheets of “DC Fix” which does exactly as in the pic, as it’s frosted to grainy, with adhesive or without.

For small lights, or in general, lights that are not to be used as throwers, it’s quite handy, and gives a nice diffuse beam like a TIR lens… sort of.

For smaller lights (eg, those which use AAs/14500s/16340s), it’s quite handy and makes a very useful beam for looking close-in.

Also, if you put the adhesive-backed film on the outside of the lens, it can be removed and replaced as needed, well, as long as the adhesive doesn’t get dirty and later refuses to stick.

‘Though for me, for smaller lights, I’d much rather TIR lenses AND NO GLUE, so that the lenses can be swapped, as TIRs come in everything from 5° to 90°. I’ve gotten the best and most useful beam with a 60° TIR lens in a 4C S2+. Beautiful “warm sunlight” beam, no fried-egg look (yellow hotspot, blue-white spill) as with the reflector.

I have 3 different-model LuxPro lights which use G3s as the emitters, and they have horrible, horrible, beams. Neutral hotspot, blue-white spill, and a strong urine-yellow corona around the hotspot. Hideous. Sick DC Fix in fact fixed that right up, but a TIR lens would do the same, had they used them instead of reflectors.

I keep harping on mfrs offering TIR lenses (yeah, yeah, AND NO GLUE), so that the beam can be changed at will by taking 5min and swapping out one TIR for another.

One last example, my Boruit RJ02 headlamp has a simple screw-on bezel holding in the TIR lens, and I can go from 5° to my favorite 60° in under a minute, no tools needed.

I’ve been looking for a TIR to try in my S2+ but it seems they’re either a fairly tight hotspot with little spill and weird beam artifacts, or an almost homogeneous beam without much of a hotspot at all. Any recommendations from your testing? I would want something just a bit floodier than a reflector setup as DC Fix is great but sometimes too floody.

Gotta order the beamspread you want, and you can pick’n‘choose what suits ya, even change it later.

Eg, my RJ02 came with what’s most likely a 30° TIR, and I replaced it with a 60°. Much better spread, zero artifacts (either the come-with one or the replacement), and more useful at close range.

90° and especially 120° do have artifacts, a ring around the periphery that can be distracting. Plus, it dilutes the beam a bit much, forcing you to dial up the output to maintain the same brightness.

So offhand, I’d say go for a 60 first, then (assuming you don’t just get a few of each type right off), go wider/narrower as you want.

is there a hole in the spot if you a SMO reflector on quad emetter array?

If there is no light emitting surface in the center of the LED array, the hotspot will look like a ring with somewhat dimmer center part (many people calls that donut hole).
Already with first generation XHP70, the missing crosshair shaped area is apparent, but with XHP50, the crosshair pattern is proportionally more pronounced, and with this quad above, it is even more pronounced.

When someone uses an SMO reflector with these emitter arrays, if the exact center of the beam is checked, one should see a crosshair shaped dark streak on the reflector as well, when looking into the flashlight (of course, very low current is needed then to check this to avoid eye injury) – this is just because of geometry, irregular things gets focused, and can be seen as beam artifacts.

For XHP70, the coarse OP pattern does its job within the Convoy L6, but for XHP50, it is already impossible to cancel this pattern with just an OP reflector, so then, SMO reflector, and this frosted lens would be better (of course, the beam will get much floodier).

And while this 3535 quad MCPCB gives even more pronounced crosshair pattern than the XHP50, sometimes this is the only solution to get good output of some LEDs with lower maximum recommended driving current – so here comes this frosted lens handy Party

And if there is not even an absence (or irregular shape) of the light emitting surface, this lens can also help with emitters, which have huge differences in tint depending on the direction of the emitted light compared to the center of beam.

I found 45 and 60 degree on Mtn-Elec, do you know of anywhere else that carries them that won’t be shipped on the slow boat?

Or was it LEDSupply? Bah, forgot.

Either one ships pretty quickly.

i can send it to you for free if you need it ,

And Simon.
For the lots of Plain torch owners out here.
A C8+ with single or triple LED. 26650 cell.
and basic ON/Ramp. Turbo. OFF. SIDE switch only.
A L2 Convoy the same would be nice tooo.
Rear switches are soo awkward I find.

Unless a person has small hands. the 26650 tube is soo much more comfortable to hold.

Hmmm. I’m contemplating if I should buy the H1 or wait for the next batch with the better UI.

Hey Simon, maybe you can sell the H1 with those “rosy” 5A1 or 5D1 XML2 from your store and I might just buy one anyway.
