I made a night light with 36 red Luxeon SuperFlux LEDs each at 53mA.
They dissipate a total of 5.5W.
I packaged them in the plastic case for a compact cassette tape and even with many air holes it gets pretty darn hot.
I have some solar garden lights with a fading RGB colour LED and a white LED. I always have them set for colours so the white LEDs were wasted.
I removed two white LEDs from my solar garden lights and installed them in my night light at 23mA each. They were a bright white for a while then they changed to a dim blue.
The yellow phosphor is gone! The heat killed the phosphor?
