My basement florescent lights are getting old and tired and the ballasts are starting to go. They aren't anything special so when the latest one started to give out, I decided to try a LED replacement. Lowes had some 4' fixtures that look a lot like florescents so I tried one out. (One only as they are about 3 times the price or at least 2 times since you don't have to buy bulbs.)
Replacement was straightforward except of course the mounting holes didn't line up to the ceiling joists but other than that, pretty simple. When I flipped the switch, I was really pleased. Much more light even though it's half the juice. Fairly even illumination, at least as good as the 4' strip florescent and instant on. If the working life is as advertised, I'll certainly continue the replacement program.
