I have a metal halide lamp which requires 2-3 minutes to warm up which i use for photo graphic exposure. i am looking for direction for a circuit that will :
1 : turn on the lamp to warm up
2: once a button is pressed, turn off the lamp after a designated time
i am struggling to get my head around this simple task, any recommendations appreciated
