I second this if there is enough space in the driver, the original modes were chosen for 3A and keeping firmware size below 1024 bytes, now there are drivers with 5, 6 and 8A, it makes sense to have more levels to cover a larger range.
0.2~0.5% mode is achievable, but due to the significant price increase of global chips, I cannot purchase high-precision chips. I can make samples, but I cannot mass produce them.
Crumpled reflector? That doesn’t sound good at all. I assume that’s supposed to be orange peel.
Does this emitter actually produce a good beam with a smooth reflector? I thought the big multi die emitters needed an OP reflector to make the beam look decent. Or is that just the Cree emitters?
yes ,crumpled means orange peel.
Russian flashlight enthusiasts are used to calling it “crumpled”. Another reason is that the two words of orange peel have too many characters, and the system does not allow me to fill in such a long word.
Even if the smooth reflector is used, the light spot is very uniform.
Using orange peel reflector, the light spot will be more uniform.
Thanks for adding M21C GT-FC40, OP/crumpled reflector with the 4000-4500K CCT seems to be a very suitable choice for me.
Just asking because I am curious. Once you mentioned, that you will design a few more flashlights with TIR lens. Did you find suitable TIR lens models for those flashlights?
The existing TIR lenses on the market are not universal in size.
Either I let the factory develop molds and design unique TIR lenses, which will cost more. Either design a new flashlight host with existing TIR lens, and design a new MCPCB.
I prefer the second option.
Your 8A driver shouldn’t be used in the Z1 as it has no thermal regulation. It works on a timer, not temperature.
After 1 minute it triggers a timed stepdown over the course of 8.5 minutes and reactivating 100% reaches over 75°C on the Z1 and behaves the same way every time 100% is reactivated, I stopped the test at 79°C after I reset to 100% for the 3rd time.
Using it on 35% mode it reached 51°C after 20 min without a step down and continued to rise in temperature.
I love this driver in the L21A, but in the Z1 it’s a bad choice since the Z1 has poor cooling.
I’d highly recommend using your 6A driver instead with thermal regulation
Thank you very much for your feedback. I think as you said, its heat dissipation structure is not as good as that of L21A. That’s why this abnormality occurs. The driver itself should be no problem. In response to your feedback, I will do the corresponding test again. Thank you for your information,
