OSRAM CSLNM1.TG & CULNM1.TG 1mm², CSLPM1.TG & CULPM1.TG 2mm²

And then you go on describing the somewhat ambiguous solution to resolve the issues…
I mean, you choose to over drive the LED up to 5.5.Amperes on a freshly charged cell, which doesn’t even add output anymore.

Sorry, but i just don’t get it.
It’s not as if there are no proper CC drivers out there.

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.

I have (2) 2S 3v17mm 4-4.5amp Mtn. Max drivers and a 22mm 2S 3v 5.5amp Mtn.Max driver I’m looking for a Push Button Host(s) for…any Ideas?

Ooh nice! Awesome host. I wish it had the choice to choose small tube for single 21700 like the size of acebeam t27.

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.

Wow, 995 available at only $9999…. I better place my order soon….

I mean those are nice drivers he mentioned. It wouldn’t be right to recommend something less than $9,999

Nice 2x21700’s hope they come out with it soon… robo…

@BobbyMk: What driver are you using

Qlite 3.04A with added 3 7135 chips and biscotti fw.

Thanks!

I’ve built a C8+ with ld-A4 at 5A and white flat 1mm

I need to tune the centering ring heigh but at the moment I’m getting 211kcd nearly 920m

Is there any similar build? I’d like to compare them and also know how many cd should I expect

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’ll start saving money for you, Lexel.
There are some other drivers i want from you too.

Same, I’ll buy one or two for sure.

Did you measure the beam with a lux meter at what distance then convert to candela?

Yes, 3300lux at 8 meters

What CC FET driver design? Think someone (TA?) did one? Wondering, not sure, if parasitic drain was considered.
