Velleman K8071 1W/3W Power LED Driver

The K8071 driver board may be compact in size, but it delivers a constant current that can support high-power LEDs. The driver can support either two 3W LEDs or up to four 1W LEDs. Simply hook the K8071 up and admire the light that it generates. With short circuit-protection and a switch mode priniciple, the K8071 operates with the highest efficiency. A heatsink is not required with this driver and a rectifier to connect to an alternating current source is built in so all you really need is the LEDs. This board does require basic assembly and soldering.
