Rated 3 out of 5 by from 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.

Rated 1 out of 5 by from 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.

Rated 1 out of 5 by from 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.

Rated 4 out of 5 by from Didn't last as long as expected! I was surprised to read that this bulb should last approximately 11 years with 3 hours of daily use. Well the lights in the bathroom lasted approximately 4 years with less than 3 hours daily use. "Unplugging" the light was a real hassle and I hope I don't have to do this again anytime soon.

Rated 5 out of 5 by from Lights! Individually these lights are $8.97, in the 12 pack they were $29.96, that's certainly a deal there. The lights work as expected (well, the 2 that I actually used, the other 10 are in storage at the moment).
