The MC35 and the MC3070 are great fixtures for display windows, or any high luminance area. Accepting 39-watt PAR30 metal halide lamps (MC35), and 70-watt PAR30 metal halide lamps (MC3070), these units produce very little heat output and lower operating costs. Alter the beam spread by adding louvers, barndoors, hoods and filters to their accessory holders.
