Modern bulbs produce light at incandescent wavelengths. They contain chemicals in the inner coating that produces a light shifted to the red end of the spectrum. Most compact flourescents work like this. Tube fixtures are produced with both the warmer reddish light and the white "natural light", which replicates daylight and produces the annoying aspects you describe. Most subway station and car lighting use these white bulbs. I have compact flourescents in every fixture in my home and I cannot tell the difference between the light they produce and the light from the older bulbs. My electric bill certainly does! |
