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).

When you buy linear fluorescents as these you might want to consider the "color" of light it puts out. Cool White (4100K) is bright white. If you have a workshop you might like these. If you need some for your office you might consider a Soft White (3000K) which are not as bright white but a little more amber and easier on the eyes.
