Rated 3.0 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by Awesome bulbs Replaced f42t8 daylight bulbs and I can't tell the difference fromeither one. How they lay a long time. April 29, 2014
Rated 1.0 out of 5.0 by Not ready for prime time I purchased 12 of these for my garage and wood shop. Removed working fluorescents and put these in. None worked and I had to return them to store. You can make excuses about not having the perfect ballasts installed, but "hassle-free replacement" means it should simply work when utilized in an already working light fixture. December 24, 2014
Rated 1.0 out of 5.0 by Don't Work Like another reviewer, they don't work in already working fixtures (Lithonia Diamond Plate from Home Depot). Fixtures are pretty new, but the the LED tubes don't work with them. December 31, 2014
Rated 4.0 out of 5.0 by Extremely bright light, and, cheaper per bulb if you buy them by the case It is much more economical to buy these bulbs in bulk, than to buy them singlely. They put off much more light than the flourescent bulbs. I would have given 5 stars, but, I had to change all the ballasts, in order for these to work with my fixtures, which I might have overlooked in the description before I purchased them. May 14, 2014
Rated 2.0 out of 5.0 by Are They Worth It? Ehhh.... Do they work, yes. If your looking for a light that just plugs in and lasts about 5 years this is perfect. If your looking for a light that will save you money and last this is not it. Look into the Toggled brand for that! November 30, 2014
Rated 5.0 out of 5.0 by Met all expectations No modification required to fixture, really great. June 3, 2014
Rated 3.0 out of 5.0 by Philips Instant fit LED tube The Philips Instant Fit how it works is piggy back on the old existing instant start ballast. Many comments on the web stated its a bad idea. The old ballast may already reach the end of its serviceable life. The LED tube rated at 50000 hours. however the old ballast may due on retire soon. At that time, user needs to replace the ballast and the tube as well. Besides, the tube is not dimmable. April 30, 2014
