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

Asked by: Lightup98852
Bring the bad-old ones to the shop (Home Depot) and show it to the clerk, they will tell you what that is for sure...

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).

40-Watt 4 ft. ALTO Supreme Linear T12 Fluorescent Light Bulb, Cool White (4100K) (2-Pack) is rated 4.3 out of 5 by 500.

I purchased this bulb to replace a burned out flourescent tube in my shop. I copied the bulb information from one of the remaining ones to be certain the color and intensity would be the same. Upon installing this new bulb and turning the fixture on, the eminating light was BLUE in color and NOT even close to the other 12 bulbs in the room. Being an electrical item, I am not sure it is returnable.

I know the issue wasn't the fixture, because the other bulb had no problem coming on completely, on either side of the fixture.

My garage is bright again....Perfect Cool White is bright enough but not overly so like the daylight white which is too much. I bought the 10 pack in case they finally do away with the T12's. I have enough for 2 decades now...hopefully. They work splendidly with hardly any warm up delay. Love them...

They are very nice and VERY bright. I need to use sunglasses now in the basement. I should have done a little more research before buying these and wish I had picked a model that was a more natural light.

Worked fine ... and at a good price compared to newer LED bulbs (which I would have preferred for energy savings ... but the brand of LEDS carried by HD were not compatible with my old ballasts).

I get up every morning before the crack of dawn to make my daily coffee,and these lights bring in such a wonderful and inviting feel ! I highly recommend this product if you desire close to perfection and near natural light.

I purchased 8 bulbs for the garage. As you may guess these are used sparingly. Yet they lasted less than 1 year.
