ThinkLite’s T5 LED tubes are the most efficient in the lighting industry. At 180 lumens per watt, they use the least amount of energy in your retrofit applications. The LED fluorescent replacement is easily and safely installed. The ballast is bypassed and inserted into shunted or non-shunted sockets of the existing T5 light fixtures. Our 22W T5 tube replaces 54W High Output lamps typically used in high ceiling overhead light fixtures or indirect lighting applications and reduces energy consumption by 70%, while increasing light levels by 20%.
