Fluorescents light up and go dark 60 times a second on 60 Hz mains electricity (50 times in the US, where mains is 50Hz). This is too fast a rate of flicker for the brain to take in, but it's there. I reckon that a steady light from a traditional tungsten bulb must be better than being in the dark half the time.

GE is now promoting what they call "Super soft light bulbs," claiming that they are better on the eyes for things like studying than the "harsh" light of fluorescent lighting.
While that may be true, I was HORRIFIED when I put one of these "supersoft bulbs" in a hallway. The hallway was transformed into a quite dingy and depressing space by the very brownish cast of its light. Careful reading of the packaging also showed that this bulb took MORE energy to light, for the same personally judged level of lighting, than the merely "soft" bulbs used previously, that gave a much cleaner and pleasant light.
My conclusion is that these "Super soft" bulbs are a giant rip-off. I don't think you can go wrong with regular "Soft" light bulbs.

Brown bulb is better than flouricent bulb to study.

For very delicate work requiring a good quality of light, use a daylight bulb. This is available from craft shops.
