DAYSTAR ENERGY REJECTION FILTER FOR REFRACTORS Electronic adapter Output: 24V DC 5A (120W)DayStar Energy Rejection Filters reduce the heat load on your filter assembly by absorbing or reflecting UV and or I light and transmitting light in the desired visual spectrum. These filters are sometimes Red or Yellow glass, or dielectric IR and UV, but pass light in the desired visual spectrum. The ERF can also serve as an aperture mask to accomplish a straight angle of incidence for light entering the filter. DayStar filter assemblies operate best
