Hoping these are better than GE LED Reveal LED bulbs.. which sucked because over a few months there was some noticeable degradation in the CRI (color rending index) and the phosphor used would flake off from inside the bulb.. plus the light bulbs made a buzzing noise....
It depends on the type, but for white light by far the most common method is using a blue LED as a 'pump' to excite phosphors, which emit their own broader spectrum and absorb some of the blue light.
They always overheat over time!
Why are they so dam high they don't last as long as they say they will last either

"phosphor" there's none in an LED light though?

Do these lights change colors
