I built up a host with 3 different colored XP-L’s, I think 1A, 3D, and 5C, and the output is fantastic! About 3800 lumens from a FET driver with TK’s ramping firmware and ramping UI. Not the simplest of builds, what with the side switch and it’s wires to get in the way, probably the MCPCB screwed to the reflector and then the reflector screwed into the head make an impact on the ease of build as well, but all in all it’s worth the effort, the supplied e-switch is on a pcb with lights already installed so if a lighted switch is one’s thing then that too should be pretty easy.
After the initial fiasco with the first version of this light (without direct thermal path board LoL) they probably decided to play it safe with these higher Vf XP-L emitters, which have a nice tint btw.
Just curious, can you elaborate about the “initial fiasco” without direct thermal path? Sorry I hadn’t read about it. So did the LEDs overheated and burned up without it?
Think they were triple XP-G3s on an Al board. Bright as all Hell, put a giggly schoolgril smirk on my mug when I first saw it, but if left on too long will, alas, cook the LEDs.
Fine for short bursts, but don’t leave it on for too long.
Think I got 3 of ’em before they were discontinued. :smiling_imp:
Couldn’t you just post that in Kronological’s K70 group buy, the one that Sofirn is taking over? (already known there, of course)
This thread is about the C8, a MUCH smaller light, with interesting developments in the C8 lineage not the least of which are the triple reflector set-up and the e-switch. Please try to stay focused…
Actually there is more involved here than you think, but which I can’t speak about. People who are interested in the C8F should also be interested in the new UI. That is all I can say.
So I am going to certain threads about the C8F and SP32A to see if anyone would be interested in talking about the new UI Sofirn is making. Its not so much about the new light.
He probably only wants to help ghost group buys out.
Back onto the main project, what I would absolutely love is the addition of an 21700 extension tube, or maybe an triple OP reflector.
That first one would make 10k lumens with XHP50.2s possible in the palm of a C8, although there would be a risk of the LEDs, even in a triple array, to be destroyed by 2S 21700s.
