Customer Reviews

48 in. T8 19.7-Watt Cool White (4500K) Linear LED Tube Light Bulb is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Works Very Well I replaced two tubes of a 4 tube florescent fixture with these. The installation was easy. especially since this replacement could be done in the room and didn't require removing the fixture. The two tubes provide at least as much light as the 4 florescent tubes. The cost was another easy trade off, as the replacing the 2 ballasts plus 4 tubes was only slightly less (about $6) than these LED tubes. If these bulbs last even half of the rated 190,000 hours, it will have been well worth the price. I have noted some comments on line in regard to a delay when turned on. The first day of use there seemed to be a few second delay (5 to 6 seconds) not really an issue. Since then they come on much faster, maybe only 2 to 3 seconds, which is better than the florescent lights. What is needed now is the same type, only in an 8 foot format to convert my garage lighting.
