That’s great, then I’d definitely be interested in a copper one too.
By the way…just wanted to thank you for this. My favorite light is my triple XP-L X6…and your heatsink made it possible. I can’t wait to make another one for my dad…he is so envious of the light!
Since he’s your dad, you should make his extra special - put 3X Nichia 219C’s in it! Sure, it won’t have the raw lumens of the XP-L’s but the tint and high CRI will be SO nice, and it’ll still be way bright!
That’s a really good idea. I was thinking about it. I believe the Nichia 219C’s that Richard will be getting in only have a 85 CRI. Do you think the tint will be that much better than the XP-L’s?
How much less output do you think I’d be giving up? I believe I read somewhere that ~ 3000 lumens are possible with a triple 219C with a FET and 30Q. Do you recall what a triple XP-L does? 3500 lumens?
I wish I could answer your questions, but I’m having trouble recalling the right answers. Perhaps someone else will chime in. Dale (DBCustom) has had experience with pushing emitters to the limits of possibility, so he can tell you what kind of output you can get from the triple, whether XP-L or 219C. Lots of people around here can give you advice about how much better the tint is with the Nichia’s. Admittedly, I’ve never used a 219C and I’m not very good at discerning tint anyway. I’m just spouting back the opinion I’ve read on here from several others that all seem to agree the Nichia is better. :bigsmile:
Dale did a quad 219c and it is currently the highest-output single-cell light in existence (at least that I can recall reading about). XP-L’s give more per amp though.
Edit: I remembered wrong. Definitely not the highest-output, but it still broke 4000 lumens (and 20amps)
My X6 quad of XP-L V6 2A does 4284 lumens @11.0A tail on a SAM 25R.
My X6 triple of XP-L V6 3D does 4250 lumens @10.02A tail on a EFEST 35A.
The triple has no glass lens (not needed), 18 AWG LED wires, 20 AWG spring bypass's, FET+1, SIR800DP FET, BLF A6 firmware.
Dale and I have the same design PVC light box, and since these lights are major flooders, I suspect our #'s are over-inflated a bit (PVC light box's can get higher readings with wide spill lights). My XP-L quad and triple did a little better than Dales, but think for good reasons - I got a UCLp in the quad, no lens in the triple, don't think he used V6 bin emitters - not sure.
Seriously think'n of putting the quad up for sale - I have no use for 2 of these....
