There is a simple explanation for why bluer "cool white" fluorescent lamps are slightly more energy efficient than redder "warm white"
Lamps. It is because
A) a phosphor wastes more energy when converting an ultraviolet photon into red light than into blue light.
B) bluer lamps use higher currents and smaller voltages than redder lamps.
C) bluer lamps operate at higher temperatures than redder lamps and produce less invisible infrared light as a result.
D) bluer lamps use higher voltages and smaller currents than redder lamps.
