Construction Recessed 9" deep housing is formed of code gauge steel and welded in a one-piece assembly for installation in a 4' × 4' ceiling system. Exposed chamfered “skirt” assembly shields electrical system with concealed lamp source. “Skirt” assembly is of one-piece welded steel construction and held in place by positive drawn heavy duty torsion springs on type “F” version.
Features • Recessed indirect coffer light provides the appearance of a handcrafted cove at a fraction of the cost • Customized appearance available with optional trim colors • Aesthetic variety provided by wood or painted steel trim • Available for type G lay-in ceilings, type F plaster ceilings, or sheet rocked ceilings
Finish Finish of interior coffer is a textured baked enamel surface. Color is a neutral cream that efficiently reflects fluorescent source output and provides a warm ambient illumination for most room color schemes. Standard finish of exposed “skirt” is baked, powder coat, matte white enamel. A variety of applied trim options to integrate with interior furnishings and designs are available upon request. For custom colors and trims, consult your Alera representative.
Ceiling Compatibility Fixture is designed to fit NEMA type G (lay-in) and type F (overlapping flange) ceiling systems. Luminaires for type F ceilings are provided with necessary adjustable wing hangers for leveling and support of unit. Labels and Electrical All fixtures bear UL recessed fixture label. Fixtures are designed for use with four lamps. Dimming systems are subject to ballast compatibility and must be quoted. CSA approval available. Use suffix “CSA”. Name: Test #: Efficiency: LER:
