Our LED T8 tubes are the most efficient in the lighting industry. At 180 lumens per watt, they use the least amount of energy in retrofit applications. The LED fluorescent tube replacement is easily and safely installed. The ballast is bypassed and inserted into shunted or non-shunted sockets of the existing T8 light fixtures. This also eliminates the safety issues associated with using ballasts with LEDs or rewiring the power to just one socket. ThinkLites LED T8 tubes are available in several wattages, shapes and lengths. With its high efficacy, it is ideal for reducing the number of tubes used per fixture. (Delamping)
