For old film projectors a new light source was needed if you want to use it for digitizing films. The old halogen lamp gives to much light (it also consumes a lot of power and becomes very hot). So I created a new LED lamp driver, that has two main settings. 0-2 Watt and 0 to 5 Watt selectable by a jumper. Within these main settings a knob can be used to set the intensity to the right level.
The size of the board is 49 * 32 * 22 mm (w*d*h)
Board can be powered by the same power lines the were used for the old halogen lamp. But can also be driven with another power source (AC or DC). The used LED is a Cree XT-E.
