Optics and Applications
This generation of high efficient, low brightness metal halide fixtures features precise new optics. Each lamp and base combination has a unique reflector system designed to optimize performance. The square downlight combines the aesthetic appeal of a small aperture in a shallow fixture profile with a smooth medium distribution. Use for general or task lighting in low to intermediate ceiling height applications.
Design Features
A sturdy steel housing protects the optical system and assures proper focal position. A microprism glass lens is standard. The trim is stabilized to prevent racking and is held to the ceiling by constant pressure springs. Maximum ceiling thickness 7/8". Top or bottom service.
Finish
Housings and structural parts are painted matte black to suppress light leaks. The shielding trim is Softglow® clear. A variety of special finishes, textures and colors are available. Refer to Squares brochure for descriptive photos.
Ballasts
Electronic metal halide ballasts provide constant output. Thermal protection with auto reset, quiet operation and automatic shutdown at end of life. For emergency back-up system contact factory.
Bases
Product performance is dependant on quality sockets to provide reliable contact to the lamp. Kurt Versen uses sockets with redundant spring systems to retain the lamps.
General
Fixtures are pre-wired, thermally protected, UL and C-UL listed for eight wire 75°C branch circuit wiring. All products are union made IBEW. Suitable for damp locations.
