【convoy】H4 and B35AM options are updated

Does S21A and S21B have the same size reflectors?

I need replacement for S21B, however in the store is only for S21A

Oh no, I whished for 0.1%mode on T2 but also 0.2~0.5% should be fine
Simon for your others FW Drivers can you consider to put 3 more groups?
0.1% 1% 10% 45% 100%.
0.1% 1% 10% 35% 70%
1% 5% 20% 50% 100%.
It will give more flexibility based on the type of driver used and limit the maximum power for extend runtime.

Can confirm that it fits.

Thanks :slight_smile: :beer:

You could just replace the driver with another 17mm driver that has whatever modes you prefer.

Thanks. Do you use leaded or lead free?

Hello Simon,

Can I ask for an option for ordering Convoy L21A with the B4-40E tint choice of XHP35 HI on the product page? (B4-40E is currently available as a separately purchased LED, but I would like to purchase L21A already assembled with B4-40E)

Also, I would like to ask that choice for the other two flashlights (M21C, M21B).

Hello Simon,
You had 18650 and 21700 battery from Samsung, Sony… in your store. Now you have liitokala batteries. Would you offer them again? Should I wait? What happened, when you do not offer them no more? Thank you very much.

Yes, they are the same.

Switching from 50% brightness mode to 100% brightness mode, the naked eye cannot perceive this brightness change.
So I don’t think this ratio is reasonable.
My suggestion is that the ratio of the previous mode of 100% mode should not exceed 40% at most.

i use leaded.

I once asked workers to try lead-free tin wire,
Work efficiency became very low, so I gave up,

CRI90 B4-40E?
I’m not sure if it can be ordered,

The current prices of these batteries are ridiculously high,
If prices return to normal in the second half of the year, I will resell them,



Aren’t those XHP35 you have in store 90CRI?

Independently of these changes, Simon, could you introduce a single 50% mode? It would be useful for the moments when a persons needs light, but not to the max (100%). It could save some battery and produce less heat too! :+1:

I think part of the problem is that a lot of people want to wring out every last lumen from an emitter that’s already nearing the top of the parabola, dumping 100% more power (and heat) into it but only getting 20% more light from it, and making maybe a 7% visual difference.

We’re back to the “numbers game” of wringing 10% more lumens by using a hideous CW emitter vs a NW or even WW emitter that just looks so much better, only now instead of quality vs quantity, it’s pushing the emitter into the diminishing-returns range of output vs input where there’s less and less to gain.

So… 50% only, for bright light that’s almost indistinguishable from 100, but get twice the runtime? Why not just back off on what’s 100 and keep it efficient? “But ours go up to 11…”

All these mode requests - it would be so easy if Simon used open-source firmware that we could modify and reflash ourselves… These drivers are all really appealing too, if it weren’t for the proprietary firmware.

+1000

Yes, I have flashed my own firmware on old Convoy drivers, but it’s regrettably not possible on the new 12-mode ones.

I think they are, and the last time I looked up the bin Simon has listed in the description, he has the absolutely best Bin of xhp35 HI, in 4000k that is. Very nice! 4000k xhp35 is probably my favorite emitter. That or xpl-hi 4000k. Output and tint are awesome
