bulb life

[P.]

Hi all,

I've had my power glo for over a year now and I think I'm starting to notice
that it isn't quite as bright as it used to be. How do I know when the bulb
is due for replacement?

Also, I've heard a lot of conversion over Sylvania's gro-lox bulb. In
comparison, how does the gro-lux bulb stand up to the power glo?

Thanks,

Phil..

conventional wisdom is that standard flourescent output drops after 6 months,
compact flourescent drops after 12.
