Excellent, I’ll add the lens to my order!

I’d rather use my flashlight around the house than turn on the lights.

Simon, is there any chance of adding additional colors to the standard anodized aluminum S2+? It would be great to see a yellow one.

Yellow doesn’t look very flattering

Hey that’s my favorite color! Wink

I understand though if it’s not worth it to manufacture since there wont be enough demand.

Do you have an estimate of when the MAO version will be available?

He mentioned that it would be 3-4 weeks about 2 weeks ago. So hopefully 1-2 more weeks if there are no delays.

Oh that titanium looks beautiful! Better make plenty of those ahead of the Christmas gift season. Smile

Great looking!

Now we need S2+ and T3 in Titanium

You can bake a grey. The end result looks quite yellow in the photo. I’ve only ever baked black, and that wasn’t Convoy either.

I would describe end result of baking grey ones as silverish golden or other way around. If I remember right it turns more silver the longer it’s baked.

Simon, what do you think about the brightest green thrower flashlight in the world?


 


LED: OSRAM OSTAR® Projection Compact, LE CG Q7WP



  • output: 900lm – 1.590lm 1.400mA input current&nbsp;</strong></li> <li>radiating surface:&nbsp;1,55mm x 2,55mm</li> <li>peak wavelength: 520nm (converted green)</li> <li>typical forward voltage Vf: 2.95V 1.400mA

  • max. input current: 5.000mA

  • projected output 5.200mA: 2.700lm - 4.770lm</strong></li> </ul> <p><span style="text-decoration: underline;"><strong>Possible driver:</strong></span></p> <ul> <li>How about a&nbsp;15A (or even 18A) constant current&nbsp;driver, i.e. three LEDs in parallel connection?</li> <li>thermal regulation 55°C

  • UI: same as 3×21A SFT40 or 4×18A SB90.2 but with some improvements (see my suggestions before)


Possible host:



  • 3×21A with triple SMO reflector (max. output would be at least 8.000lm or up to 14.000lm, depending on LED flux bin)


Actions required (from my point of view):



  • price ratio and availability of LED to be checked

  • gaskets/centering rings would need to be redesigned

  • correct alignment of the LEDs on the z-axis to be checked (“how deep in the reflector hole will the LED be?”)

  • reflector geometry would need to be tested once again (maybe no changes necessary?)

  • driver from 4×18A SBT90.2 might suit well here?


For reference, the design of Convoy’s 3×21A SFT40…



 


Datasheet (in Mandarin):


https://dammedia.osram.info/media/resource/hires/osram-dam-15551339/LE%20CG%20Q7WP_CN.pdf


 



I’m currently trying to throw together the brightest green thrower of all time, with the help of the LEDiL Seanna and the OSRAM LE CG P2AQ , I’ve tested the seanna optic before with the CSLNM1.F1 and got some impressive results. The LE CG P2AQ can spit out up to 13K lumens at full tilt (15V 10A), at least with the bin that mouser sells, which is the lowest one, some of the higher bins can go 17K+, all of this from a 2.6*3.2mm light emission surface. The emitter should arrive tomorrow and I’ll post some beamshots once it’s all finished. I’m anticipating this one to be one of the greatest throwers of all time.

If you're gonna do something, do it in style!
If you're gonna light up a city, do it in 95CRI+!

I hope the switch is metal (can't see for sure from the photo). And if it's metal switch, is it stainless steel, or titanium as the rest?
Will there be a T3 version?
Any output graph? The aluminum t4 version did hold over 40% output.

Nice review stephenk and interesting info on the strobe. Thumbs Up

I’d rather use my flashlight around the house than turn on the lights.

Hello Simon. Have you ever thought about building side by side 2×18650 or 2×21700 light? Batteries would sit similarily than shells in double barreled shotgun.

I have long dreamed of such an inexpensive flashlight. Rectangle, two small reflectors or TIR-optic for 2*XHP50/70 and 2*21700.

!{width:55%}https://ae01.alicdn.com/kf/S0872133482c74ad8bd2ff6b3ad32df958.jpg!

Seconding this suggestion :

  • The side by side design allows to make a compact multi cell light that isn’t too long or too thick thus it is more pocketable than 2S tube lights or 3P/4P soda can lights. That is if the head isn’t thicker than the body, or at least not significantly.
  • It can deliver a lot of power efficiently in 2S configuration with a 3Vout buck or 12Vout boost driver, covering all different LEDs. >4.5Vin offers many options for powerful and efficient buck converters and allows more power with a boost converter as well.
  • Same point about the LEDs, for example with 2 side by side B35As which when used alone aren’t super bright, or 2xXHP50.3/XHP70.3 HI for max raw output.
  • 2S configuration isn’t dangerous if inserted incorrectly unlike 3/4S, it will just not power on, I remember you mentioned safety concerns about the abandoned 3S 21700 7xXHP70 project.
  • It is a change from cylinder lights, which are very common and I believe the only shape offered by Convoy. I think it’s possible to make pretty slick designs with this shape if one is inspired enough.

An example of a flashlight in this format is the Klarus RS30BA (2×18650)

Regarding assembly, the head, body and tailcap are held together by a threaded rod and knurled nut.
Same assembly in the Frelux Synergy (2×14500) : https://budgetlightforum.com/node/73446

Anyone else with an L21B experience the o-ring trying to come off with the tail cap?

Every time I unscrew the tailcap, it tries to pull the o-ring up and off with it.

Sucking it up into the threads and I have to be careful not to damage it.

Solution seems to be that I have to unscrew the head instead.

Heres a photo showing the tailcap starting to be unscrewed, and the o-ring is half out of its groove and being pulled up into the threads.

@TIFisher Thanks.

I guess this is just normal for this light?

They’re just pretty thin guage o-rings. I have a bunch extra. Try unscrewing the cap 1/2 turn at a time, tightening back a hair each time. Good lube helps, too. I use Super Lube O-ring lubricant (liquid).

Thanks again for the suggestion and info.

Doesnt seem to fix the problem for me though, so i’ll just continue to open it from the other end.

I dont have any extra lube to put on it right now.

Will there be a titanium T3? What about a titanium 18350 tube for the S2+? Looking forward to both! The T4 is just too long to fit comfortably in my pockets.

Hey! When will the stonewashed T4 be back in stock on AliExpress?

Also, how different is 2700K from 3000K for this emitter? Any reason to choose one over the other?
