I installed T8 fixtures in my new garage shop last fall. The heat did not "go
in" until Feb and the units lit up like incandescents. They take a little while
to get to full brightness and heat, not that its in, does help them get there
faster.

They do cause some radio interference on my favorite radio station - a very high
pitched whine. That may be because the radio is on a shelf right up by the ceiling.

I choose the T8s not because of the startup, but because they are supposed to
produce more light for less money. Just a Scotsman I guess.
