I want to simulate the suns rays striking the surface of the moon for an astronomy club. My idea is to use two lamps either led or bulbs, (led preferred) placed 90° apart or 45°either side of the vertical where a camera will point down on a crater surface. Turning a rotary switch will dim one lamp while brightening the other so that at the mid position both lamps are equally lit. This will show the change in shadow detail when viewed from above.
Could anyone please assist me in the circuit required as I just can't work this out?
Many thanks
