Using super bright high-power LEDs and intelligent power control, Eco-$mart LED Tubes replace T8 and T5 fluorescent tubes with an energy efficient, mercury free light source. High Quality LEDs are very stable and long term testing in extreme conditions prove their reliability and durability, which dramatically reduced maintenance costs. A wide voltage design ensures application in all countries. With over-load, over-voltage, over-current and over-heat protection, power supplies and controls are protected. These LED fluorescent tube replacements are in accordance with CE, UL, and CEC testing standards.
