flourescent tubes Question
 

What's the difference between a flourescent tube of "regular" circumference
and a "slim" tube with pins of the same configuration? Are they
interchangeable?

The larger diameter lamps are T-12 and use magnetic ballasts and the smaller
diameter ones are T-8 and use electronic ballasts. They are not
interchangeable and the electronic ones are more expensive but work much
more reliably. FYI the number in a bulb i.e. T-8 refers to how many eighths
of an inch in diameter the lamp is
