This  LED panel light is designed for residential and commercial ceiling surface mounting and suspended grid ceilings. Because its driver is built into its frame, the panel can be mounted directly to junction boxes. Use this dimmable 2' x 4' LED panel light for home lighting, office lighting, basement lighting, light box and sign backlighting, school lighting, hospital lighting, and more! Replace existing fluorescent troffer light fixtures or use for new construction applications. With LEDStripInHut technology and an optical diffuser, the LED panel light delivers a smooth, flawless wall of illumination without visible bulbs or hot spots. Bright and powerful—the 40-watt LED light emits 4,500 lumens of natural white illumination—equivalent to the output of 2 32-watt fluorescent T8 tubes. The LED panel light 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 5 times longer than fluorescent panels. Includes a 0-10V dimmable constant-current driver. Brightness can be controlled with a 0-10V dimmer or by using the light's step-dimming (power-cycle dimming) feature. Mounting options include either a surface-mount kit for existing J-box installation or a light-specific J-box for recessed-mount wire enclosure.
