Answer: 
Yes, these used to be the best "looking" bulbs you could buy, with a CRI of 92 - and 5000K is not too "warm" - yellow - or "cool" - blue. However, for the last year or two when you get to the store you find Philips has changed their spec and this is now a 90 CRI bulb. Still way better for your kitchen or foyer or laundry room than a CRI 75 shop light, but 90 CRI bulbs are available at many more places Read More

Rated 3.2 out of 5 by 5 reviewers.
Rated 1.0 out of 5.0 by worst tube ever I bought the ten pack for $40.00 that had a LAST 7 YEARS" written on the package. a year and a half latter all ten had burned out. I called Philips about the warranty and they told me not to turn them on and off so much. they told me they would send me a check for $12.00. not bad for a $40.00 investment. August 12, 2016
Rated 4.0 out of 5.0 by really feels like natural light Feels like natural light. Took some getting used to since its in our stairwell and usually on at night. December 16, 2013
Rated 5.0 out of 5.0 by Florescent light bulb 10 pack Excellent value. Best way to buy if you have multiple florescent fixtures. January 5, 2016
Rated 1.0 out of 5.0 by The packaging claims "lasts 7 years", failed after 16 months. The 2 bulbs I bought in April 2012 were on for less than about 1000 hours when they failed, compared to the 24000 hour life printed on the packaging. Bulbs are dead as of August 2013, after just 16 months, much less than the 7-year life also printed on the packaging. August 18, 2013
Rated 5.0 out of 5.0 by The product, light bulbs, were average quality but that is all that we needed The ability to order this product on line and receive it in a timely manner was great. August 21, 2013
