ThinkLite’s 360 LED T8 light fixtures are the most energy 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 passed and inserted into the existing shunted or non-shunted sockets in the tube. The double sided, 360-degree Dual Shine Tube line emits light 360 degrees, enabling retrofits of direct and indirect fixtures.
