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

4 ft. T8 32-Watt Natural Light ALTO Linear Fluorescent Light Bulb (2-Pack) is rated 3.9 out of 5 by 13.
Rated 5 out of 5 by from Easy to install, work great, provide a great deal of light Easy to install, work great, provide a great deal of light

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 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 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 4 out of 5 by from 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.

Rated 1 out of 5 by from Burns out fast Burned out after 2 years. Pretty weak considering I installed a brand new ballast with these lights. Phillips will send me a check but, I would have preferred to have them last 10+ years like the previous ones. Going with GE or Sylvania next time.

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.
