I don’t know where I screwed up but a de domed xhp 50 turned blue on me once . I can’t remember exactly what went wrong but if I remember correctly, the complete dome came off.

White LEDs consist of a blue LED with a layer of phosphor on top.

When hit with blue light the phosphor emits red and green. This, combined with some of the blue light from the LED that passes through the phosphor is where you get the red, green and blue light that makes up white light.

If your LED turned angry blue after a failed de-dome it means you took too much off. Basically you accidentally removed part or all of the yellow phosphor layer revealing the underlying blue LED.

Thanks. I wasn’t trying to slice it. It just came off with the reflector hitting it. I was bummed after waiting a month to get it from China. Anyway, went back to the original xhp50 but sliced it. CCT dropped a little which was what I was after.

Well, I have one of those Xml2’s also in my parts bin.
