Construction & Design

The smooth matte black trim features a fade- and scratch-resistant finish. A steel heatsink supports thermal performance, while the UV-resistant polyester trim ring frames a frosted acrylic lightguide that distributes light evenly without hotspots. The fixture weighs 1.4 lb. The dimensional drawing shows 12 in diameter, 9/16 in panel thickness and 1 1/4 in overall height.

Light Output & Performance

The integrated 22W LED delivers 1,650 lumens, with a listed 100W incandescent replacement equivalency. Select 2700K, 3000K, 3500K, 4000K or 5000K at the fixture DIP switch to choose a warmer or cooler appearance. Its 90 CRI and R9 greater than 50 support accurate color rendering. The rated 50,000-hour L70 lifespan avoids routine bulb replacement.

Electrical & Installation

The driver-on-board design avoids a separate rear driver enclosure and allows installation on most common junction boxes. Its thin panel keeps the visible fixture close to the ceiling without a pendant-style hanging drop. Connect to 120V at 60Hz; input current is 203mA. Compatible TRIAC/ELV dimmers adjust brightness down to 10%.

The fixture is UL listed for indoor or outdoor dry, damp and wet locations and is not IC rated or airtight. Select the desired color temperature at the fixture DIP switch during installation.
