The 7027 BuckToot LED Power Module is a true constant current regulated driver for LEDs. Unlike standard power supplies, which deliver a fixed voltage to the output, the BuckToot LED driver is designed to reliably vary the output voltage as required to deliver a stable constant current to the LED(s). The BuckToot exhibits very high efficiency and does not require external current limiting resistors or additional heat sinking.
