Rated 3.0 out of 5 by 5 reviewers.
Rated 3.0 out of 5.0 by Adequate but not as bright as orginal I bought these to replace bulbs in three light fixtures. I thought the bulbs would be the same as I originally had in the fixtures but found the lumens were different and the output was a cool light. Bottom line is the amount of light output is less and a different type of light than the original. It serves the purpose but I am not too impressed with the bulbs. I didn't see any other lumen choices and thought when I searched for the 12 in. T9 32-Watt Cool White Plus (4100K) Circline Linear Fluorescent Light Bulb I would be getting the same thing I had. The brand is different and I don't remember the lumen or wattage of original. Bottom line is I will live with it. July 1, 2014
Rated 5.0 out of 5.0 by Works fine. Good value when bought in bulk. These are good standard bulbs. I was surprised to learn that it cost the same to buy four individual bulbs as to buy the box of 12, so of course I got 12. I suggest getting together with friends. December 17, 2014
Rated 1.0 out of 5.0 by Flimsy and burn out fast Two have already flickered and then died. Construction is flimsy, wear gloves and eye protection to be safe. Price was good but probably not worth the hassle of replacing every couple months. August 21, 2013
Rated 1.0 out of 5.0 by Questionable I bought a case because it was the best deal. The cost per bulb was about $2.50. They arrived 9/6/13 and I had to replace one on 9/13/13. The wire inside had broken. It may have been do to rough handling during shipping. If I had bought one bulb for $13.97 I would have been very dissatisfied. September 13, 2013
Rated 5.0 out of 5.0 by Great Bulb No issues so far. Got the lot for a great price. These have been knocked in some reviews think they should check their ballast. March 12, 2014
