I made this dimmer circuit because I have a cheap chinese LED lamp that doesnt have the option to dim its light. It is a simple PWM dimmer built with the well-knows 555 integrated circuit and a power MOSFET transistor to drive the LEDs. The led lamp shown in the video is powered from a 3.7V Li-ion battery that lasts longer compared with the original one that was a 4V/600mA type.
