Customer Reviews

4 ft. T12 40-Watt Cool White Supreme Linear Fluorescent Light Bulb (10-Pack) is rated 4.6 out of 5 by 8.
Rated 5 out of 5 by from Made a big difference At the time, I was only going to replace the one burned out bulb. However, the price for the set of 10 was too good to pass up. I decided to replace all the bulbs in the garage. This made a huge improvement. So much so, I replaced the bulbs in the laundry and utility room.

Rated 4 out of 5 by from Casts good overall light quality for replacement bulbs in garage, basement, & laundry areas. Still testing first set of bulbs in replacement locations for surviving duration; but overall quality of light cast from these bulbs equals or exceeds most comparable lights for intended garage, basement, and laundry areas at this time.
