A cheaply made bulb doesn't really support your theory though. Before LEDs, the anti-bug yellow incandescent bulb was available. It puts of a horrendous light and most people didn't like them. It's in the top 3 of lights that I do not like: 1) anything CFL, 2) any cool white (>3600K) light at night, 3) ugly yellow anti-bug light, 4) whatever the ugly greenish light 7-11 uses at some gas stations, 5) 4300K fluoro tubes.
