Rated 5 out of 5 by It works! I put them in and they fired up perfectly will install more. November 11, 2014
Rated 1 out of 5 by garbage lights I'm lucky to get a month out them. I won't by sylvania again November 11, 2014
Rated 5 out of 5 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 4 out of 5 by 20% DOA 2 out of the 10 tubes would not light right out of the box (20%). To me, this is pretty poor quality control. November 4, 2014
