The Goldstar air cooled reflector is a well designed air cooled unit. For those who have used an air cooled supernova, this is a big improvement, better designed with a vastly improved closure system.
It has an excellent seal around the edge and a wire safety cord. It has a 150mm aperture on each end for a decent air flow across the lamp. Overall, a high end air cooled unit for those situations where heat control is paramount.
