Rated 3.5 out of 5 by 20 reviewers.
Rated 2.0 out of 5.0 by High out-of-box failure rate Bought 3 cases of these bulbs to do a refresh of our gym at my church. So far, I've had a 30% failure rate right out of the box. Bulbs were dark-patched or flickery like the old ones that had to warm-up on a magnetic ballast. Brand new ballasts and did bulb swapping to make sure problem was with specific bulb and not some other factor. If I was not well into this project, I would return all the bulbs and go with a different brand. I may still do that with the remaining ones. December 16, 2013
Rated 5.0 out of 5.0 by great lights the lights are inexpensive, they seem to last a long time in a commercial setting, the light is just right February 11, 2015
Rated 1.0 out of 5.0 by 33% Garbage I know with that low-mercury bulbs need a few hours to achieve full brightness, but one third of the bulbs I've tried out of the box are total failures and never go past dim. Those that do light up are inconsistent in color, some being warm and others being bluish. Don't waste your time on these. January 25, 2015
Rated 3.0 out of 5.0 by T-8 Fluorescent bulb Happy with service, good price on t-8 tubes, would use Home Depot again. January 13, 2015
Rated 5.0 out of 5.0 by Awesome! We are sooo glad to find a resource for our lights! December 17, 2014
Rated 5.0 out of 5.0 by good product excellent life span on a 4100 cool white tube. So, why pay extra for a product that can last for years. December 11, 2014
Rated 3.0 out of 5.0 by Tubes are good, but packed badly so some arrived broken. The summary says nearly all of it. I called when I opened the box and found what seemed like missing tubes. No, they were at the bottom of the channels, broken. I called immediately, and replacement tubes were supposedly to be shipped immediately. I realized a couple of days ago that they have never arrived. If the tubes had been in stock at a store I would recommend, but not if you have to have them shipped. February 18, 2014
Rated 4.0 out of 5.0 by Cool white lights The lights are quality manufactured and are easy to install. They provide excellent illumination for the cost. September 30, 2014
