Interesting. Thanks.
Wondered what was up when my 12v leds started showing up with yellow tops. My older ones were all crystal clear. I take it that different phosphor can put out different colors, not just white?
Hey, whatever works. Gonna have to find an old bulb and compare the light output vs a fresh one.
