Sledge,

I found something wrong with this website. In fact, its in one of the first sentences in the paragraph about blue bulbs.

"White light is made up of every color of light mixed together."

WRONG. White the color, is the absence of pigment. Webster says "white" is "free from color". BLACK is every color mixed together. We did an expirement in oh, 3rd grade or so that proved that. If you put some dye on a strip of black paint, you get all sorts of colors on that strip.

I made a mistake in saying that color and brightness go hand in hand. What I meant to say was that color temp in Kelvin and the amount of "blueness" go hand in hand. As the color temp goes up, light (NOT BULBS, strictly light) appears more and more blue. A blue tinted bulb however, screens out everything BUT blue, which wouldn't make it any brighter than a non tinted one. Lumens is the correct way to measure brightness correct ????
