Bring clean, adaptable illumination to offices, retail stores, and commercial interiors with this ETL Listed LED flat panel light. Its slim rectangular design, white frame, and broad illuminated surface create a streamlined ceiling appearance without bulky hanging fixtures. Measuring 47.75 inches long × 12 inches wide × 1.22 inches high, the panel offers a low-profile solution for compatible suspended-ceiling installations.

Customize the fixture to suit your space with 20W, 30W, or 40W selectable power settings using a DIP switch. Choose a lower wattage where less output is needed or a higher setting for brighter illumination. The 3CCT-selectable design also provides 3000K, 4000K, and 5000K settings, allowing you to choose a warmer appearance, balanced neutral illumination, or a cooler daylight-style effect without replacing the fixture.

For additional brightness control, the panel supports 0–10V dimming, with the supplied dimming graphic showing an approximately 5%–100% brightness range. Wattage selection establishes the fixture’s operating power setting, while a compatible 0–10V control allows brightness adjustment during use. Its AC 100–277V input range accommodates projects with a compatible electrical supply.

The installation images show fold-up mounting brackets and a rear wiring compartment, supporting an organized installation within a compatible ceiling grid. Use this panel to create coordinated lighting across open-plan workspaces, showrooms, retail displays, reception areas, and corridors, with selectable wattage and color temperature to match the needs of each area.

    The 0-10V dimming works smoothly and gives us a lot more control over the lighting during the day.

    The selectable wattage is a really useful feature. We used 30W in the smaller offices and 40W in the larger work areas without having to order different fixtures.

    We replaced several older fluorescent fixtures in our office with these and the difference is huge. The light is much more even, the ceiling looks cleaner, and we were able to choose the color temperature that worked best for the space.
