A double-sided LED lamp includes a shell, a plastic circuit board (PCB) and an optical film. The shell is made of translucent or transparent material. The PCB includes a number of rows of LEDs for emitting light beams, and defines a number of rows of through holes. The optical film facing the LEDs can reflect some of the light beams through the number of holes and also allow some of the light beams to pass through.
