Are pink lamps hotter than blue lamps?
Another common misconception is that the color of the lamp affects the tanning. UV is what tans you, and it is too high a frequency for you to see. (some birds and insects CAN see UV, but not humans.) The color of the lamp is determined by a mix of phosphors that has NO effect on the tanning. You can take any tanning lamp, and make it glow green, yellow, purple, red, pink, blue or even different colors, and that will not change the tanning in any way. The main purpose of the color is to please the eye and differentiate the lamp from other lamps. That is all.
