LAMAR LED, LWT, Recessed Mount Lighting

LWT Series

Backlit LED Troffer Series

Lamar’s backlit LED troffer provides even illumination with no LED imaging. Powered by state-of-the-art LED technology to ensure even illumination across the panel while highly efficient acrylic diffuser provides maximum light output.

Free from the “hot” edges commonly associated with today’s flat-panel products. Suitable for grid ceiling installations, surface box kit available. The LWT series is available in many lumen/wattage packages, driver tuning is fully customizable to meet your specific requirements (2×2 up to 6000 Lumens).

The LWT offers the look of contemporary lighting and the efficiency and low maintenance of LED technology. An ideal choice for use in offices, hospitals, and schools.
