Hi all,
Some years ago, whenever the SSC P4 U-bin emitters were the latest brightest emitter, I purchased one and modded my MagLED drop-in bulb replacement, replacing the Luxeon with the SSC P4.
The light has been off and on from time to time since then and produces a lot more light than the original MagLED. However, I have noticed that the silicone dome or gummy or whatever you want to call it, has started to develop a brownish tint to it. It is still quite transparent I suppose but tinted brown a bit.
Any ideas what could cause this? The tint appears to permeate the silicone, it's not just on the surface. It appears there is more tint closer to the die of the LED.
Is this a sign that the emitter is getting too hot? I can't see any difference in beam tint so far, it's still the cool white color I'm used to seeing. My understanding was that the MagLED drop-in didn't drive the emitter all that hard, and that it used a temperature sensor to down-regulate the current if the drop-in got too hot. Seems kind of strange that the gummy dome would turn brown from heat, if that's what it is...

. The process has progressed very slowly, I assume.
