Rated 3.9 out of 5 by 34 reviewers.
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 replacement lamp replacement was easy enough and with the greens being environmentally friendly they dispose of quickly September 18, 2014
Rated 1 out of 5 by started failing within 2 months, almost all burned out within a year, and killed 2 ballasts Bought this 10 pack last year for a kitchen with 8 bulbs. Within 2 months bulbs started failing, getting black marks on the ends, and one of the 4-bulb t8 ballasts failed with a pop and burning smell. The ballast brand was "Advance" which also seems to be made by Phillips. Also put the bulbs in a 2-bulb T8 garage shop light, and that generic ballast immediately popped with a burning smell. Within a year maybe 2 bulbs are still working, both with black marks. Replaced the failed ballasts with GE brand ballasts that are still working so far, and trying Sylvania t8 bulbs now from the L store. October 15, 2013
