Multi mode LED driver board 350mA 4.5 - 6V

Driver board designed for PETZL head lamps using a Luxeon 350mA 3W LED. These boards have three modes, full brightness, economy mode and flashing. Can be used to flash parallel arrays of up to 20 standard 5mm LEDs which are Blue or White in colour as the output is approximately 3.3 volts and perfect for these LEDs. Not difficult to piggy-back other switches instead of the board mounted ones.
