I’m refurbishing a dive light and would like to install 4 pcs. of XHP50.2 (or XHP35.2 if it’s more doable)
I’ve a problem with choosing a proper driver(s) for this project. I have 11.1V 3S li-ion battery pack that I’ll be using to power the leds.
The actual light frame has quite small hole to fit driver(s) 24mm diameter that is 32mm deep.
I’ve tried to search for suitable driver but to avail.
Can you suggest me something that could work within these limitations?
Xhp50.2 are 6v or 3v emitters and the xhp35 is 12v. To run those xhp35 efficiently you’d ideally need 4S input on a buck driver or fet driver. You could do a buck driver for running 3v or 6v 50.2 on 12.6v. I don’t know of any 24mm drivers like that, but there are plenty of 20-22mm and some 26mm up to 32 to 46mm that would power your emitters. You could possibly fabricate a retaining ring or adapter in the driver pocket to get a smaller driver to work.
if everything else fails, you got enough room to stack 2 drivers, or even more, power leds separately, or in pairs, but it will be impossible to control modes, so go for 1 mode drivers, it is not like dive lights need modes anyway
To my knowledge, 50.2s are actually 12V or 6V emitters depending on how they’re connected to the mpcb. There exists a special 3V version which only comes in 6500K and maybe 6000k
50.2 in theory can be run on both, but the most common are 6v. The 3v version existed in 5000k, 6000, and 6500. I have a 5000k K2 C3 bin I got from Kaidomain in January that’s not in their store anymore. I can’t find the 5000k anywhere now. Shame because that’s an incredible emitter!
