Rated 1.0 out of 5.0 by These lights do not last - Their warranty is only 6 months, not 18 years! I have had 11 of 20 of these T12s burn out far short of their life expectancy. In my home, I wanted the daylight look as "warmer" (in other words, yellower) lights bothered me. My home was built in 1985 and features the 4' T12s througout. I have other brands of those warmer lights from the early 1990s STILL working! None of those older tubes are the Philips brand... These new "Alto" (aka "low mercury") lights fail considerably sooner than the old-school tubes. It cannot be the ballasts' fault as I have moved those older lamps to the fixtures and they are still working. I called Philips and their warranty only goes to 6 months, not 18+ years, so buyer beware. Since the daylight tubes are more expensive, I suggest trying another brand if you want them to justify their price because these tubes were an utter disappointment. May 23, 2014
Rated 4.0 out of 5.0 by This product Worked Great for me I had several failing lights in my closet.The bulbs were not getting bright as they used to which made dressing and picking clothes very difficult. I purchased these new at Home Depot, installed them and problem solved. In fact they are brighter than the previous bulbs April 9, 2014

Rated 5.0 out of 5.0 by Let there be light... It's a fluorescent tube. I installed and got great light. Actually, I do like these bulbs. I use on garage and shop/tool room settings. Get a good clean light from them and they seem to work wonderfully in cold environments. July 30, 2013
Rated 5.0 out of 5.0 by Love these light bulbs I bought them, put them in, and never had a problem since. They are bright (just the way I like it) and they light up right away. No buzzing sounds. March 25, 2014
Rated 5.0 out of 5.0 by Great Light We use these in our kitchen, though there are 4 of them in the unit the light is bright but not irritating. Will purchase again. March 18, 2014
Rated 4.0 out of 5.0 by Nice white. Good light for a dim basement. It's a daytime white so we have to match the other lights to this, but worth it. March 18, 2014
