Customer Reviews

Feit Electric 4 ft. 18-Watt T8/T12 32W/40W Equivalent Cool White (4100K) G13 Bypass Ballast Linear LED Tube Light Bulb (4-Pack) is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Makimn the change Easy to convert to LED T8 bulbs from convention fluorescent tubes. I did this in my kitchen light which has 4 fluorescent lamps. It was easy to strip the ballast out of the fixture and unneeded wiring. I used 1 X 1 wire tie mounts and wire ties to secure the new LED bulbs in place. The connectors that comes with the lamps makes it a breeze to connect the new lamps to the line side. My kitchen has no outside lighting so theses new lamps should keep me off the ladder a lot more.
