I just bought the host, driver, lens and the spacer(kiriba-ru) for throwing together an EDC Convoy S2+ with triple LEDs, but I’m stuck at the emitter choice.
The plan is to run each one at 2A, regulated, I hope to have similar brightness throughout battery life.
4000K or a bit below, and also high CRI would be a welcome bonus
I’m aware that I won’t be able to run it at full power for long, does anybody know how much can the S2+ take for longer periods?
The numbers can obviously be kinda off since I took the numbers from emitters of different color temperatures and CRI, but I think it shows the point
SST-20 has a tad low efficacy from what I’ve seen on the tests, but people say it has great color rendering
(3.12v at 2A, 540lm)
(3.005v at 1.4A, 400lm : 74%)
I like the higher output if the 351D, but the brightness at low battery levels seems to go way down
(3.23v at 2A, 922lm)
(3.12v at 1.5A, 727lm : 79%) - still more than the SST-20 at same voltage
(2.99v at 1A, 514lm : 56%)
The 219C could provide the most linear output
(3.04v at 2A, 605lm)
(3.01v at 1.75A, 546lm : 90%)
219B
(3.12v at 2A, 506lm)
(3.02v at 1.25A, 360lm : 71%)
It’d be best if I can order them from a site like kaidomain, preferably pre-soldered onto a PCB , but I can try doing it myself if that’s not possible
I’ve read that the 219C has a great tint, but some say that the 351D’s is better, but I haven’t seen any side by side beams,
Does anyone have identical lights except the emitters?
Any pictures, suggestions or advice would be greatly appreciated
