12v/20watt halogen lamp.It is possible to limit power. When red light is on it means current is limiting. You need to turn current higher and in parallel lower voltage if getting too high!Weird supply

ericbeekers Thisis normal behavior. You are in constant current mode. Not constant voltage mode. The power supply will try to keep the current constant and if needed will higher the voltage to keep the current constant.
