Rated 3.1 out of 5 by 10 reviewers.
Rated 2 out of 5 by The one I got appeared to be "used" When I got home with the bulb and took it out of the package, which appeared to be opened before, the bulb had dark spots at each end reminisence of a used bulb. It worked, but for how long, remains to be seen. August 5, 2014
Rated 2 out of 5 by Bulbs are disappointing Bulbs do not last very long and I have to change them too often. August 5, 2014
Rated 5 out of 5 by Under cabinet Lights LINEAR Fluorescent bulbs Easy to install and alot cheaper priced than the other brands. Last just as long July 3, 2014
Rated 5 out of 5 by Good Color I still like fluorescent over LED or halogen. I get good color and long life. Philips quality is as good as you would expect from a major mfg. I'm old school I guess. January 29, 2014
Rated 5 out of 5 by Great replacements for original fixtures that failed The fixtures were easy to install and performed flawlessly. Because Home Depot had a variety of products to choose from, product selection to fit my needs was easy and immediately available. January 14, 2014
