Nothing against proper CC drivers but nothing bad with FET DD either.
5.5A with constant and proportional current drop like in FET DD setup is not overdrive. It is just fine… So natural current drop with FET DD also means less temperature stress plus FET DD does not generate any heat on driver board while CC linear does generate?
Where can I get a 21 mm or 28 mm CC driver at 5.5 amps running decent e-switch firmware like NarsilM or Anduril with as low, or lower parasitic drain? I do really want to know because I can't keep up with all the goin's on.
I'm confused because since when is a 17 mm power switch driver the only one we need? Granted, it's the most popular but for my usage, it's still in the small minority of flashlights I have or am interested in.
Yeah, you’re right.
Limited choice.
Not sure what Lexel has to offer though.
As for diameters, you could use an adaptor ring of some sorts.
Either way, i’m looking for e-switch 17mm FET CC drivers.
I don’t care too much for elaborate UI’s though.
3 modes usually suffices for me.
I will work on D1S and likely some other sizes CC FET drivers, but this will take 5-6 weeks at least to get to production if first design works out well
I’m very impressed. My C8 (BLF A6 DD, NCR18650B) is easily hitting houses at 800m distance(measured with Google maps). That’s the holy grail of LEDs for throwers.
Can’t imagine how the D1S will perform.
