Customer Reviews

Rated 2.5 out of 5 by 2 reviewers.
Rated 3.0 out of 5.0 by Failed after 3 years Bulbs worked well for 3 years and then one failed and the other one started flickering. The reason I give it 3 stars and not 1 star is because Philips actually stands behind their 7 years warranty and they were quick to send me a check to cover the purchase price. Even better, it was easy and it only took 3 minutes on the phone, no on hold music, no hard to navigate menus. October 17, 2013
Rated 2.0 out of 5.0 by Not bright enough as a single Bought these to go in a single fixture light strip over a work bench. For this application these are not bright enough. May work better in a double, or it could be the "Cool White". March 6, 2013
