16 in. T9 40-Watt Cool White (4100K) Circline Fluorescent Light Bulb is rated 2.6 out of 5 by 5.
Rated 2 out of 5 by from seems dim The bulb works but it seems dim. My light fixture holds 2 bulbs -- one 12 inch and this 16 inch. The smaller one seems brighter even though it is rated for less watts

Rated 1 out of 5 by from Horrible Product Replaced both bulbs in a kitchen light. It's used as much as any other light. Also replaced starter ballast. Bulb's gone bad in 4 months. Phillips warranty system says they won't accept your return unless you kept the packaging and the receipt. So, there is NO real warranty unless you can predict that it's going to fail and keep there packaging around for 11 years.

Rated 2 out of 5 by from Poor product life Bought October 2013, stopped working July 2014. Package says lasts up to 4 years, I didn't even get a year. This is the 3rd one I've bought. Guess I'll be going for a different brand. And yes I did read that the lifetime is effected by how many times it is turned on and off. It is generally turned on only during cooking and in the middle of the night. So its time on is limited to maybe 3 hours a day and is turned on maybe 4 times in a 24 hour period. :(

Rated 3 out of 5 by from repeat purchase It would be nice if a warmer fluorescent bulb was available. This one has a very harsh light, very industrial for use in a home.
