For you David… I don’t think we ever got the Knucklehead working… not for long anyway…

oh, not trying to call you a knucklehead just reminiscing about the drivers those guys came up with… this one was one of Matt’s I think (MattAus)

342

Yeah, back then I couldn’t understand anything you guys were talking about with those drivers, so no surprise I don’t retain any knowledge from those times. I “remember” the knucklehead driver, but I don’t know anything about it unless I go back and read about it again.

343

I kinda got pushed into thinking about these emitters a little while ago, and the idea came to me to use the White Flat’s in a reflectored triple. I like small well made lights, anyone know where I can get a good price on a Brass MecArmy PT16? :smiley:

344

Thank you for the information about the drivers.
I thought: Hm, PLZ that is “Postleitzahl” (= German for postal code), maybe its something else. :slight_smile:

345

I put something together
testing out the right values for the CC part will need some testing
the 2 blank copper areas are to solder a piece of copper wire likely hammered flat to spread heat better

346

So, this driver needs a heat spreader? Wow! :open_mouth:

Thanks Lexel! Are you planning to build/sell these? If so, when do you think it will be done testing and ready to buy? :smiley:

347

You should sell these to Hank so he can make D1S with White Flat.

348

Hank is right now not interested in white flat D1S, I tried to offer him driver but he said

it may happen later we will see

349

hmmm I wonder why. Seems like there should be enough demand. Maybe he’s having a hard time centering/focusing it?

350

when will this be ready for order? also will it be a 5A buck driver?

351

Any news on a CC driver I can fit in flat white D1s?

352

Any updates on your driver, Lexel?

I put one together, albeit much more rudimentary than yours. 5x CN5710 (dual channel: 1+4) for 5 amps linear. Working good so far. Without any reflector height tuning, got 958 lumens & 273k lux with a Flat White 1mm² (vs 1540 lm & 127k lux stock driver with XP-L HI)

353

how much for this driver? and do you ship to Thailand?

354

I need to do more testing before I’d consider selling them. I sometimes ship internationally. But international package shipping from the US is quite expensive too, ~ USD $13.54 just for shipping.

355

13usd is fine as long as it works

356

while the driver is being discussed, how does my recent purchase compare performance wise to what’s being tossed about here…?

Click

357

About the same.

358

Thanks BlueSword… I hate to miss out on something… This thing is pretty dam impressive for such a small light… !

359

What does 8 amp pulsed mean. Even if I use an ncr18650b or equivalent cell it’s still not safe for the osram 1mm??

360

I can sell a few prototypes
Price as usual is 12€
Anduril or NarsilM as firmware

shipping is 1.4$ from here untracked
5$ tracked with 25€ loss insurance

v2.0 I made some minor improvements from the original prototype

any recommondation what to change?
