Looks like Digikey has the domed 70.3s (XHP70D-00) in stock, including 90 CRI versions. Would be interesting to see some tests of those.
No sign of the XHP70.3 HI (XHP70D-H0) anywhere, though. Definitely looking forward to the 90 CRI versions of that one. Mouser claims to have an ETA of April 8, but no idea how accurate that is.
Hey guys. Has anyone been able to find out if we will have different options with xhp50.3 hi 3v? I mean 80+ cri/warm light. I met information that it only works in the 6 volt version. Hope this is a mistake.
You’re probably correct. The bin code is 50G x=0.3447 y= 0.3553 duv looks to be slightly negative. But it’s a 3 step ellipse so a lot of variation is possible there. I have 8 of them on the way so I’ll let you know.
Great info, thanks all! I ordered a couple of xhp50.3 hi variants from kaidomain (90 cri 2700k and 5000k, and 80cri 4000k).
So what kind of currents can these handle? 18W in the 6V configuration (with a convoy 20mm xhp50.2 driver) seems like babying it. Hank’s b35am dm11 driver seems to give around 22W (6A measured at tailcap): that better. How about feeding it 30W?
I might have to plug one on one of my cheap variable buck drivers and visually gauge the point of visually diminishing returns.
Thank you. I was wondering if being domeless made a difference. Also, it also apparently has improved thermal conductivity, so the efficiency curve could could be a bit higher.
In any case, going off the 50.2 tests, it seems like 18W and 22W are reasonable.
