I am only talking about LED bulbs for household lighting and not LEDs in general. Without exception, these LED bulbs contain only blue LEDs coated with phosphors. An obvious question is "Why not buy phosphors and coat blue LEDs yourself as part of a DIY project?" The answer is that the phosphors are expensive and sellers have large minimum orders. For example, see

If I were a billionaire, I would coat LEDs for fun, but, sadly, I am not.
