Arclite ED17/7 is an efficient 7 inch aperture downlight. It is designed for use with the 50, 70, 100 or 150 watt medium base ED17 metal halide lamps approved for open fixtures, and is equipped with an electronic ballast. The fixture provides a shielding angle of 40 degrees. Precise reflector design minimizes aperture brightness. One basic housing allows interchangeable use of downlight and wallwash reflectors. This permits housings to be installed first and reflectors installed or changed at any time. Reflectors are available in clear, natural aluminum in two finishes: EvenTone, our standard clear finish, partially diffuse, anti-iridescent and gently luminous in appearance; and EasyTone, diffuse and luminous. Additionally, reflectors are available in champagne gold, wheat, pewter, and bronze. Wallwash (120 degrees), corner wallwash (210 degrees) and double wallwash (2x120 degrees) reflectors are also available.
