Eco Series LED Tape Lights use high brightness 2835 SMD LEDs, the typical current for these LED is 60mA and output 0.2W. But we lower it to 30mA and 0.1W for ensuring the best performance and lifespan. Eco series use 3/8" width premium double side flexible PCB (2OZ canlerdar cooper layer + PE film) which is thicker and wider than most competitors, it will create much better heat conduct performance.
