Wow. In terms of tint and efficiency, this LED is boss.
2.88V at 1A. Perfect for extremely efficient triple LED builds.
No, until 17mm boost driver are available.

I was getting ready to order a 4000K XP-L2 for a Sofirn SP32A when I came across this, I see this is only a test for tint/CRI but I’d like to know how would this compare to the XP-L2 as far as output?
I tried to find info in the spec sheet but couldn’t, I’m used to the Cree datasheets, guess I just need the simple answer
Ok, this is the first official release of an LED test from my setup. I have a few others already complete that I will be releasing as I get the time to make the charts all pretty and ready for upload.
Cliff notes version
- My sphere and setup is finally calibrated to a level that I feel good about releasing numbers from
- I figured out how to turn a PVC sphere into a true integrating sphere that reads the lumen value directly on the lux meter so no math is involved
- The lumen readings line …

It has been a long time since Lumileds released an emitter that was really appealing for flashlight use. In fact, ever since Cree smashed all prior existing performance with the introduction of the XR-E, the Luxeon leds never took the lead again. The tints (at same CRI) of the Luxeons were always good, and superior (IMO) to the Cree leds, but the performance lagged behind. So how about the new Luxeon V ? (confusingly there already used to exist a Luxeon V led in the old days, it is a bi…
112lm/w 5A
But in direct drive with same config that powered xp-l2 with 5Amps you will get something like 7.5Amps with 86lm/w.
For linear drivers like LD-*4 you can just compare lm/Amp. 1653lm XP-L2 vs 1820lm Luxeon V, both @5A .
