I am designing a target board for my paint ball game. I plan on using an ambient light sensor to actuate a small led light strip to either come on or go off when the light sensor is covered with paint. I have a light sensor made by Vishay (TEPT5700) that may work. The tech at Vishay stated that it only needs light to work, though the documentation sent to me stated that a load resistor of 10 ohms will produce 3-5 volts. I do not want to damage it so I am asking if anyone may know the size load resistor I should be using. The led lights work off of 12v and produce 24watts of power. I used an online calculator to get the other 2 answers - 2 amps and 6 ohm load resistor. Is this correct? I am not an engineer, I know enough, not even, to be dangerous..thanks for the help..
