I did forget about this phenomenon, I do remember reading this in the datasheet. I did take these when the emitters were cool. Actually thinking about this, I can try again when they get warmer but the setup I am using is designed to make sure they do not get 85°C or even that warm to the touch.
Just ordered some 2700K XP-L HI’s from Mountain Electronics. I’ve used 3000 and 3500k before quite a bit but never a 2700. Probably not a drastic difference.
I really do want something 2200K and under. But I also did get some SST20 2700K from kaidomain! Going to give that a try and see how they turn out. Probably in an acebeam headlamp
You can go for the 2200K Cree XT-E or or the 2500K Osram Oslon SSL-180 for 3535 drop installed. They don’t have the best appearence though, 80 CRI only. My 2700K XP-L HI turned out to be closer to 3000K in the SMO Convoy C8.
I’ve ordered the FW3A copper, and will be sticking some 2700K SST-20’s in it, can’t wait.
nice! just ordered fw3a too and will put the sst20 2700K in it too. seems like that’s the lowest cct and highest CRI option we have for a 3535 footprint
People are on about “look at how candle-like this 3000K XP-L HI is” with their Anduril lights, but the Copper FW3A, Anduril Candle Mode, and finally candle colored 2000K LEDs…yes the actual copper candle. Not to bash on Djozz
Samsung offers LM302Z+ mid power LED with CCT down to 1800K. CRI80 only.
Not that it’s some great option but that’s an option. Clemence sells compatible MCPCBs.
