Convert your existing fluorescent fixture to LED technology with the Feit Electric T96/840/AB/LED 8 ft LED dual-mode linear lamp. This non-dimmable T8/T12 replacement produces 5200 Lumens of 4000 K daylight color temperature light using only 42 W - up to 29% less energy than an equivalent 59 W fluorescent lamp. These versatile bulbs can be used either as a plug and play replacements using existing ballast or can operate without a ballast after basic rewiring of the fixture.
