I just put 7 of the 219B 9080 LEDās into a SRK with the stock non-DTP mcpcb.
I can legitimately say that I am blown away by the tint of these! I have seen quite a few LEDās and this by FAR blows them all away.
These are the whitest, purest, most gorgeous LEDās I have ever seen! Keep in mind that over half of my lights are 90+ CRI.
Even compared to all my 219B 9050ās I have, these have no noticeable tint shift either green or red. Just pure amazing white. All my other 219bās have a slight shift to either the green or rosy side.
I was worried when I saw these outside of a reflector when on the bench that they would be too rosy but seems it was just an effect of having tested the 319A right before it and that screwing my frame of reference.
Now I will see what it looks like tonight to get a better idea but at this point I am in love, I just wish that they had higher output.
A 219C 9080 would be perfect, if only they could put the Phosphor from the 219B 9080 on the 219C die it would be the perfect LED for all your CRI needs. Hmmm, maybe they would be open to a special run of these clemence?
Only downside is the low output but in triples and quads it is perfect. An M34 or M43 would be amazing with these.
Now on the down side, DO NOT use these with non-DTP mcpcbās. I killed 3 of the 7 LEDās I installed in the SRK. I am not sure if it is a mismatch in the Vf or just not being able to get rid of the heat. Either way 4 are nearly dead and released magic smoke. I now have to run the light with only 1 laptop pull cell installed to limit current.
Oh wow, sorry you smoked some. Iāve only used one of mine and I put it in a pretty weak light (a 1 amp HDS), but I absolutely love it. TA isnāt exaggerating folks, theyāre that good. Iāve gotta figure out what Iām doing with the rest of mine.
There are some sm503 9080 D220 ādomelessā 219C on my desk right now .
Unfortunately no sw45k available at the moment. And theyāre the hardest LED to solder Iāve ever had. No thermal pads, even the super tiny cramped solder points are well hidden under the die completely.
Do explain, how does a 219C not have a thermal pad? Donāt they call the version without a thermal pad the 229C or something like that? Without the thermal pad it is basically useless for a flashlight sadly.
Although I would gladly take a 219C 9080 in 5000k, 4500k would be my preference but not going to argue over 500k!
I find the sw45k significantly rosy, but shined on anything but a white wall that just makes all the colors look extra rich. After my eyes adjust all other light sources look greenish and pale.
The sm503 is a little cooler than I expected. Itās unambiguously cooler next to other 5000K 219Cs and an XHP35 HI in 3C. sm503 left, 3C right
The 3C definitely has a touch of green in it. sm503 does not, and what I may be seeing here is the lack of off-colors more than anything. Also, Cree hotspots tend to be warmer than spec while the spill is cooler. Regardless, these are nice, and do, indeed look like a very pure white.
