The Feit Electric LED 6 inch T8/T12 U-bend LED Linear Tube light bulbs 4-pack make it easy to convert your existing fluorescent fixture to LED technology. These versatile bulbs have flexible installation options either direct plug and play using the existing ballast or with simple rewiring of the fixture to bypass the ballast. The LED bulb has a life expectancy of up to 50,000 hours and can operate in existing fluorescent fixtures that have a 2-pin G13 connector. It produces a similar fluorescent lamp output of 2100 lumens, using 15W of electricity up to 53% less energy than a standard fluorescent lamp. This 4000K cool white light is non-dimmable and eliminates the flicker and humming associated with normal fluorescent lamps.
