Rated 4.5 out of 5 by 6 reviewers.
Rated 5.0 out of 5.0 by 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. September 16, 2014

Rated 4.0 out of 5.0 by light bulbs Not sure why Home Depot would send me an email rating light bulbs, but okay......... These bulbs make light when there was dark, provided you send 110V to them. August 19, 2014
