All lights flicker its just a matter of whether or not the eye sees it. Incandescents flicker 60x a second, FL tubes near the end of their lives when the ends get dark and the draw more power are slowing down. This might be different with CFLs and tubes with electronic ballasts.

Ahh - gotcha... Older ballasts will flicker at 120Hz for those with 60Hz service (and 100Hz for those with 50Hz). Electronic ballasts move that frequency way up - on the order of 40KHz-120kHz (this is the "flicker free" designation)
I really haven't noticed the characteristics of a bulb on the outs (I've only had one go in ~7 years
) - so I can't comment from experience with end of life flickering...
If those frequencies are bothersome for anyone.... Holy crap
Watching movies must be an excruciating experience

"glare" as opposed to being "bright". hmmmm, trying to think of a great way to describe it. You can have a light that is bright and sharp like a halogen, metal halide and another that is dull (glare probably isn't the correct term here) (FL, cold cathode, low pressure sodium) with them both being giving off the same amount of light. There is a qualitative difference. I guess the more proper terms should be dull and sharp. You can be bright and not necessarily have glare.

Not sure I follow - glare is a synonym for brightness... But I can't figure out the word you're looking for :/ No worries
