Default My own question about fluorescent lighting....

Hi, I've been reading here for a while and now have a question. I have
a t12 25 or 40 watt shoplight fixture (48 inches) on one of mytanks, is
it true I can use t8 bulbs with it as well (I am assuming the t8 bulbs
would be required to be 48 inches long and 25 or 40 watts in power)?
Please confirm - thanks all!

Nope. I wish I could say so authoritatively but I'm not 100% aware of the
reason. I *think* it's because there's different striking and burn voltages
and frequencies. Maybe somebody can confirm.

Wright Huntley knows for sure. It might be in the APD archives. God knows
everything else is.

Default My own question about fluorescent lighting....

Hi..

Hmm.., as far as I remember we continental Europeans used
those thicker tubes until the 70s (80s?) and that we were
later able to use newer (and thinner) T8 tubes in our old
lamps..

You can drive T12 tubes with a T8 ballast but not vice versa
if I read this correctly.

T8 tubes can be used in "standard" fluorescent fittings... been using them
for decades, just swapped over to "normal" electronic ballasts for my new
tank.... with T8s !!!
