How can you tell what type of lighting fixture you have? ie: T8 or T12

what bulb is good for the garage? Cold in the winter.

Asked by: Rick
The new T8/T12 LED 4ft light bulbs at Home Depot will work great in the cold and produce a ton of great light. They also will not flicker like the old style lights. The have the perk of using less electricity as well. Win Win all the way around...

Are these bulbs dimmable?

Asked by: SamB
No. I tried two different brands of dimmer switches and neither worked for my 50 bulbs in my basement ( all on same circuit.) I sure wish they were dimmable, because my basement lights up like WalMart ( too bright).
