Customer Questions & Answers

What is the CRI number?

Asked by: Mini
Color index is 82 but these Philips lights are garbage due to failing way too quick. Look at another brand like GE

Can u use this for growing plants indoors

Asked by: therandomperson
I'm not sure if it gives off the right spectrum of light for optional growth. I guess it would depend on the kind of plants you want to grow. Some plants make use of any kind of light and others need true sunlight or specific grow light.

When we updated the old fixtures in our kitchen we chose natural light over conventional fluorescent. The light is easy on our eyes and makes the kitchen brighter then before.

Rated 3 out of 5 by from 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.

Rated 5 out of 5 by from SUPER BRIGHT Very bright. Love 'em. Glad i went with 2950 lumens. If you want brilliant white light, these are the ones.

Rated 5 out of 5 by from 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.

Rated 1 out of 5 by from 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.
