CUSTOMER REVIEWS

Rated 4.0 out of 5 by 11 reviewers.
Rated 4.0 out of 5.0 by Great Product! Great product. Nice and bright. Will be using them for my seed starting. Two cons though- 1.) The bi pins were a little loose surprisingly. 2.) The packaging is actually difficult to get off the product with worry of damaging the bulbs. February 19, 2015
Rated 3.0 out of 5.0 by Lumens Specifications Listed Incorrect This item only produces 2850 Lumens not 2950. Also the model number ending 664 refers to 6500K Daylight Deluxe Bulbs which are also 2850 lumens;. However they do have a 10 pack off 6500K Daylight Deluxe that specify 2950 lumens as LT85's. I've spent over 100 dollars to get bulbs that specifications listed are not met. Using spectrometer and digital light meters. Still I've managed to get close to what is needed for my project, but what a waste. In the end it would have only cost me around 40 dollars if the specifications listed were anywhere close to item specifications. July 25, 2014
Rated 5.0 out of 5.0 by Bulbs and ballast must match FYI. T8 bulbs are not a drop in replacement for T12. When switching from T12 to T8 bulbs the ballast must also be switched out. April 23, 2015
Rated 2.0 out of 5.0 by Lasted 3 weeks then both pooped out. I found 2 beat up old lamp fixtures in my uncle's storage, one had tubes the other didn't, so I bought these at Home Depot. The 20+ year old tubes had been running for a month before I bought the Philips Alto pair from HD, I'm using them to grow my pepper plants inside. Well the Philips pair just went dark within 48 hours of each other 3 weeks later, and the old tubes are still going strong. I guess they dont make em like they used to. December 29, 2014
Rated 5.0 out of 5.0 Very good for bedrooms or any other location in any house hold. i bought these for a shop light i bought for my bed room and they are very bright they light up the whole bedroom with one bulb i would recomend this to anyone who is looking for a bright light like these.

Rated 1.0 out of 5.0 by Stay clear of this brand The bulbs failed after less than 100 hours, not only the first time but the 2nd and 3rd time, yes, I was a sucker and replaced them over and over, thought it may have been the fixture, replaced the fixture and the bulbs failed again, I contacted Phillips to inquire about the problem, was told that I may be operating the light improperly, really, how does a person turn a light on or off improperly? Go with another brand if you want to see in the dark. January 28, 2014
Rated 5.0 out of 5.0 by SUPER BRIGHT Very bright. Love 'em. Glad i went with 2950 lumens. If you want brilliant white light, these are the ones. February 14, 2012
Rated 5.0 out of 5.0 by Very bright! I found this lights to be about 50% brighter than my previous 40 watt T12s. Very good for the kitchen and any other place where natural light is needed. I just hope it lasts as long as they say it would. June 2, 2014
