Rated 2.6 out of 5 by 5 reviewers.
Rated 1 out of 5 by If You Want To Waste Your Money Than Buy This................. These last about a year or slightly longer. These are GARBAGE and cannot believe they are being sold at Home depot. August 12, 2014
Rated 2 out of 5 by Lasts About One Year!! Purchased one about a year ago and already went bad. The light was used in the kitchen. Everyone in the house works or goes to school and the light is not left on when no one is in the kitchen. This is a poor product Home Depot should stop selling, particularly with the outrageous longevity claim. September 18, 2013
Rated 1 out of 5 by Low Quality Junk and Overpriced These bulbs are junk. If you find one that hasn't been damaged in transit, it will only work for a year, as opposed to previous ones that lasted 15 years. The manufacturer is building obsolescence into these bulbs so they don't last long and they can sell more. They are flimsy pieces of junk. March 24, 2013
Rated 5 out of 5 by kitchen light bulb I purchased this light bulb for my kitchen and have no complaints. It produces very nice lighting so I would buy again. February 25, 2014
