The Advanced Control Unit is a professional timer & contactor system for turning on 4 x 600w lights. Design and build quality are the watchwords here. This system will turn on 4 x 600w lights in groups of 2 with a 25 second delay between each group. The benefit of this is that you do not have a large start up power surge by turning all the lights on at once. This is relevant as a light typically requires about 20% extra ampage to 'start up' as opposed to when they are up and running.
