I use most of my surplus LEDs to lights up the garden, the streets close to my house, even the sewer in my front yard. Still waiting for Sedstar’s package for the 4500K XPGs.
Just got chouster’s package in yesterday, so no. And I feel that Texas Ace has has already shown what the 319 can do, so there are no leds atm that I’m planning an output test on.
We’ll try to be better next time. No confusing reservations, long wait time, etc….
Hopefully we can get you less than 7 days delivery service after whenever you paid the order……worldwide (or at least in USA, Asia, and Europe).
I will try to test all the LED to Maukka first for less guessing and post purchase disappointments (it feels bad on my ends you know ).
Still trying to get cheaper pricing by collaborating with some big manufacturers here….
And to make everything much simpler, only one order page/front page for all areas.
219B and 219C were measured at 700 mA, 144 at 1400 mA.
I have tabulated the results using both a diffuser (Convoy) and a reflector (Reylight Pineapple one for the 219B/C and Nitecore TM03 one for the 144)
All the tints from the hotspot with a reflector:
219B/C from the hotspot and midway through spill (very small tint shift):
144 from the hotspot and midway through spill (clearly a larger shift):
Superbly neutral tints from all the emitters. The 219B sw45k R9080 is clearly more magenta but in real life it’s not bad, makes for very vivid colors (high TM-30-15 Rg index). Highest ever CRI I’ve measured from the hotspot of an led: CRI (Ra) 97 and R9 97.
The 144 are also very consistently amazing. Just pure white goodness. Even though the color temp shift is higher than on the single die emitters, the tint stays at the black body radiator line. Diffused they are absolutely perfect. With a reflector I measured significantly cooler color temps (about +700 kelvin) from the hotspot, but that doesn’t matter if you know what you’re getting.
I haven’t put any of these to a flashlight yet so cannot comment on the real life applications, but so far I’m very impressed.
Thanks to clemence and chouster for sending these!
Looks very good. Especially the 144AM. I wasn’t wrong about them
Interested in testing the 319As and NVSL219B-V1 sw40? I’ll ask Chouster to send them to you later
EDIT: I’m not a fan of 219B tint, but I never thought the CRI result is super amazing. Now I know why this one is so special for you guys.
Did anyone yet put a high CRI 144A in a flashlight with smooth reflector yet? My single sample produces an ugly yellow spot in the center of the hotspot, but it has a slightly uneven phosfor layer, perhaps other’s leds are better?
No no, don’t worry, this is another led with a much better phosfor distribution. But even a slightly uneven distribution with the phosfor just a bit thicker (=more yellow) towards the center (my led) already produces the effect in a smooth reflector (have not tried OP yet).
Ahhh, I see…
Yes, smooth reflectors aren’t the 144Ax mates. I tried them in my predator’s reflector, many narrow TIRs, big reflectors, etc…always a slightly yellow center spot. Fixed easily with even very mild 5 degree diffuser. All medium, wide, and diffused optics worked great. I’m sure OP reflector will do OK since this the artifacts in 144Ax are much less problematic than XHP50
