LED wall packs project a bright, clean light and reach full brightness instantly. They use LED lamps, which last longer and use significantly less energy than wall packs with other lamp types, such as high-pressure sodium or compact fluorescent. They also produce very little heat and can withstand temperature changes and humidity. These wall-mounted outdoor lighting fixtures are commonly used to replace traditional lighting on commercial and industrial buildings. Wall packs are wall-mounted outdoor lighting fixtures that are typically used to illuminate large areas, such as commercial building perimeters and office complexes. They cast widespread light to provide added visibility and can help deter theft, crime, and unauthorized access to perimeters. They are also a good choice for doorway and loading areas in need of extra security lighting.
