Construction & Design

The nominal 1 × 1 ft square panel features a white metal enclosure, smooth trim and a polycarbonate diffuser that distributes light evenly for general illumination. Its 15/16 in profile keeps the surface-mounted fixture close to the ceiling without a pendant drop. Fixture weight is 2.0 lb.

Light Output & Performance

The integrated LED produces 1,700 lumens at 20W with 85 lm/W efficacy. 90 CRI and R9 at least 50 support accurate color rendering, while 4-step consistency helps coordinate multiple fixtures. Select 2700K, 3000K, 3500K, 4000K or 5000K using the DIP switch. Rated life is 50,000 hours at L70, and separate bulbs are not required.

Electrical & Installation

The constant-current Class 2 driver accepts 120-277V at 50/60Hz. The panel is designed for surface mounting, with family-listed compatibility for 3 or 4 in junction boxes. Its slim form avoids hanging clearance, making it a practical choice for lower ceilings. The individual sheet specifies indoor dry and damp applications and states that the fixture is neither IC rated nor airtight.

Choose a compatible TRIAC/ELV dimming system for brightness control down to 10%. Set color temperature at the fixture DIP switch during installation. The sheet also lists suitability for closet use under NEC Sections 410.16(A)(1) and 410.16(C)(1).
