Rated 3.7 out of 5 by 46 reviewers.
Rated 4.0 out of 5.0 by best fluorescent light bulb Easy to install they also are very bright and last along time, very satisfied. April 28, 2015
Rated 1.0 out of 5.0 by They don't last. I installed two 4-bulb fixtures in my garage. Usage averages less than 2 hours/day. The light level when new is fine great but 4 of 8 bulbs died within a year. I am switching brands. April 19, 2015
Rated 1.0 out of 5.0 by JUNK Worst lights ever. Have used 6 of these in different rooms. Longest one lasted 70 days. Also half the lights do not light up in the middle of the bulb. Total waste of money. April 1, 2015
Rated 4.0 out of 5.0 by Timely purchase - just what I needed/wanted. Just one question. Both the light fixtures and the bulbs were ordered on the same day - but they arrived almost a week apart... December 23, 2014
Rated 4.0 out of 5.0 by Fluorescent Lamps work fine and arrived when promised! easy way to get products March 10, 2015
Rated 3.0 out of 5.0 by It's light bulbs, they work 2 out of 7 boxes were damaged, but a credit was issued and all is well. March 3, 2015
Rated 5.0 out of 5.0 by Not too yellow, not too blue! I first tried this cool white bulb in the two pack before committing to the larger 10 pack. It hits the middle ground in providing light that isn't too warm nor too cool on the light spectrum. I use it in my laundry room where our two bulb panel is able to illuminate stains well. In our garage, we have this 4100K light next to some much warmer 3500K lights that cast a yellow or peachy glow. Although color discernment isn't as big an issue in the garage as in the laundry room, the 4100K also provides more (perceived?) brightness which is a plus when poking through bins of screws. This might be better contrast due to the whiter color. The next highest light yields a light that is way too blue. September 23, 2014
Rated 5.0 out of 5.0 by Light Bilbs We bought new light fixtures and had to purchase light bulbs for them. these are pricey. but apparently they last for three years. we will see about that! December 30, 2014
