The M40 is a lens-less system that combines the benefits of Fresnel and PAR fixtures. It is open face and offers a brightness that is about 30% higher than the AS40 in spot. Its unique MAX Technology reflector allows for a focus range of 18 to 52° Half Peak Angle, giving a consistently even beam spread and crisp shadows. It is designed for 4,000 W lamps, but can also be used with 2,500 W lamps.
