I didn’t test higher because it’s a quick test without heatsink, anyway the tint is sunlike (0.0033), or slightly greener at lower current. Disappointing that it’s not closer to the BBL
The beam looks quite good even with SMO reflectors.
At 0.1A with KR1 SMO reflector :
spot : CCT = 4605K (Duv 0.0033)
Corona : CCT = 4191K (Duv 0.0067)
spill : CCT = 4383K (Duv 0.0032)
for the data thefreeman. Cree is not the new Nichia but it looks decent, 90CRI Cree’s that I have seen before were awfully green (that was before I had a spectrometer, so I can not back that up with duv numbers), this sounds better.
Maybe I’m not so good at reflowing, but these XHP50.3 HI 4500K 90CRI LEDs seem to be rather fragile when it comes to current. I went just above the limit on two of them at 12V and they burned out rather quickly. My heat sinking was probably not adequate either but for now I I’ll give up on these until someone who knows what they are doing does a more thorough test.
I got a 6v XHP50.3 HI doing 4k lumens I think the current draw is like 8-9 amps it’s okay but I’ve only used it for testing. I tried to reflow one and the dome melted.
