The Simple Panel Light is great for dental office lighting, hospital lighting, classroom lighting, waiting rooms, basements, and more. Because the panel's driver is built into it's low-profile frame, the light can be surface mounted on walls or ceilings. It can also be mounted in suspended grid ceilings. The image is printed directly on the 2' x 2' or 4' x 2' LED panel diffuser. This backlit panel uses Even-Glow® technology and an optical diffuser to deliver a smooth, flawless wall of illumination without visible bulbs or hot spots. Bright and powerful—the 40-watt dimmable LED light emits natural white illumination. The LED skylight operates within a wide 100-277 VAC range, has a sturdy aluminum alloy frame with a white or black finish, and is designed to last at least 3 times longer than fluorescent panels.
