【convoy】H4 and B35AM options are updated

Any info about the availability of the SFT-40?

So, once again… I have to sing the praises of Simon and Convoy. My S11 FC40 developed an odd driver issue, on mode option 1.2 the 2 low modes worked fine and the three upper modes were all the same dim brightness and the light was always indicating low battery voltage. Contacted Simon about the issue since I wanted to be sure to get the correct driver ordered… he just sent one.

Put it in today and the S11 is as good as new. I really like this one and the M21B with the FC40, would hate to not have either one of them.

Thanks for the excellent service Simon!

Simon Will you be getting any more green 18350 body for s2+ with trapezoidal thread?

the threads will be unified into rectangular shape, so I have no plans to continue to produce 18350 tubes with trapezoidal threads,sorry

I’d be a lot more interested in how these outputs are holding up after a few minutes.

I can test this sometime but in theory the bottleneck of the thermal pad should be apparent on very short timescales. Longer tests basically should show the difference of the thermal path further away from the led.

Heat starts at the LED junction then goes through: Die > Substrate > Solder > MCPCB > TIM > Heatsink > Air. Anything after the MCPCB should not have an impact in any difference between the two packages. My strategy for testing this would be to actually float the MCPCB in air and do an output test that way at saturation temps. The only thing I can see making a difference at longer timescales is the loss of the thermal ‘driving force’, i.e. the delta Tj and Tmcpcb.

The tests that I do though are pretty aligned with real-world use though. Always open for debate, but let’s do that in another thread maybe :+1:

Hi, newbie here.
I thought best the ask here.

I’m planning to order S2+ with LH351D (5000K or lower) or maybe SST40…
My question is, what is the different between “Ar-coated glass lens, Smooth” vs “Glass, Orange peel” lens.

I have a flashlight with TIR optic and I really like it. Shall I get also some TIR optics? Is it hard to change by myself?
(Also there are 4 different option type on Convoy store. Bead, flat, matte and striped with several degree)

Thank you so much!
Any suggestions will be a big help :slight_smile:

Lens type: Ar-coated glass lens
Reflector: smooth
—————
Lens type: Glass
Reflector: Orange peel

I’ve created a new post here with some of my thoughts on how Convoy’s user interfaces can be improved. I would love for the rest of the community to take a look and tell me what you think, and I also hope Simon will take a look and see if any of these improvements are feasible.

Hi Simon, it has been more than 2 months since the announcing of Quad TIR and it’s production.

How is the progress?

I got the sample some time ago, and the host is already in production.

Nice… :+1:

Hey Simon,

  1. Any idea when SFT40’s are going to be back in stock?
  2. Also, do you have any plans for adding charging to more lights, such as the M21B?
  3. Will the Remote Tail Switch for the L21B also work for other lights, such as the M21B?

Thanks a lot for how you help the community!

Simon,

I recieved my M21e today, such a nice light!

I installed my sft70 LED in the s21b xhp50.2 light and it worked fine on mode 1-3, turned blue on mode 4 (100% output).

I then installed the SFT70 into my m21e and it worked up until about 75% ramp, then turned blue and the light started smoking. I thought i blue the sft70..

But now my m21e wont turn on with the xhp70 in it either. I put that back in and it wont work.

Can i buy just the driver for the m21e from you?

does anyone know what i did to my driver? i wouldve thought that just the led would burn out if anything, and i was completely OK with doing that for the sake of expirementing.. I didnt think it would ruin the driver..

Anyway.. TIA

Simon, any idea when SFT40 will be back in stock?

even for sale in your lights again -

Lights with sft40 like the m21a, m21c, or L21a?

Thank you!

I always check if I put led wires wrong way if nothing happens after install. Or if you reflowed it to pcb 180° wrong way.

I got my AA/14500 13 group drivers, I also got an orange T3 with an SW35. The stainless screw on clip is way better than the stock clip.

The wires on the 14500 driver are backwards. The red is negative and the black is positive. All three were this way.

Unfortunately I broke one of the drivers tightening the retaining ring in my Jaxman E3. The pliers slipped and broke some stuff off the back of the board. Double sided drivers may be unavoidable, but they are annoying.

I also put one into a Thorfire TG06, It works perfectly in that light as well. It’s also sold as the Alonefire X380. Same host with slightly different reflector.

How is rosy sw35 from Convoy compared to others like Azhu’s?

The only 219b I bought from Azhu are the SW45K. The SW35s from Convoy are my first. They are very nice though.

Post #6000!

(at the moment.)

Nice! :beer:

You got #5000 as well, if I remember correctly.
