What is a Wall Pack Light?
A wall pack light is a wall mounted lighting fixture which provides illumination and security around the exterior of buildings during evening hours. These lights are commonly used around walkways, back entrances, mandoors, and other areas around building perimeters. Wall packs were traditionally designed as HID and fluorescent fixtures; however, LED wall packs are now available as a more energy efficient and eco-friendly alternative.
Common Types of LED Wall Packs
LED Wall Pack Applications
Wall pack lights are commonly found on building exteriors to illuminate areas around the perimeter such as walkways, paths, exits, etc. Common uses for LED wall packs include but are not limited to the following,
- Outdoor stairwell lighting
- Exterior lighting
- Car wash lighting
- Storage Unit Lighting
- Parking Lot Lighting
- Parking Garage Lighting
- Gas station lighting
High Voltage Wall Packs
High voltage LED wall packs are popular for large applications requiring significant illumination, especially when they are mounted from high above. These lights are ideal for multi story buildings with tall exterior walls, as well as large retainer walls and other high structures. These wall packs feature higher powered LED chips with exceptionally robust driver technology, all housed within a durable alloy case and impact resistant lens.
LED Wall Pack Installation
Wall packs are typically installed either via wall mount or junction box. They are hard mounted, meaning they utilize solid fasteners to affix them to their structures. Wiring to the fixture itself is typically through conduit mounted either externally or within the wall or vertical surface itself. It is recommended to work with an experienced electrician during install to ensure that they are mounted correctly and to the relevant building codes.
LED Wall Packs v.s. Metal Halide Wall Packs
While these fixtures look similar in appearance, they are vastly different in terms of performance and energy efficiency. One of the most apparent differences between these two lights is the actual quality of the light produced itself, with LEDs offering a much higher CRI rating when compared to traditional metal halide technology.
When combined with built in dimming capabilities for custom tailoring lumen output for the specific ambient lighting situation, LED lighting is clearly the superior choice for wall pack lighting applications. UC Davis discusses these benefits in their assessment of their own experience in upgrading to LED wall packs from outdated metal halide tech, stating:
“Wall packs typically employ high-intensity discharge (HID) light sources, such as high-pressure sodium (HPS) and metal halide (MH) lamps. These sources are only moderately efficacious, contribute significantly to light pollution…Replacing inefficient sources with LED or induction technologies and adding photocells, occupancy sensors and controls to wall packs dramatically reduces this energy waste.” (University of California, Davis, 2012, Adaptive LED Wall Packs)
Wall Pack Frequently Asked Questions
Q. What is a wall pack light?
Wall pack lights are wall mounted outdoor fixtures that provide illumination around building exteriors at night. These fixtures are the most popular outdoor commercial light in the United States.
Q. What is a photocell?
Some LED wall pack lights come with a dusk to dawn photocell. This allows the fixture to automatically switch off during daylight hours in order to maximize energy-efficiency. It’s important to note that not every wall pack comes with a photocell or is photocell compatible so it’s important to check the product descriptions and specifications prior to buying.
Q. What Wattage LED is Equivalent to a 250 W Metal Halide Wall Pack?
While dependent on the manufacturer, in most cases a 250W metal halide wall pack is equivalent to a 100W LED version. While there is a big difference in energy consumption, illumination output is equivalent thanks to the highly efficient technology behind LED fixtures. Also, because LEDs are unidirectional, they can be more efficiently used to direct light instead of requiring extensive reflectors to redirect a metal halide bulb producing a 360° beam pattern.
Q. Where are wall packs used?
These outdoor lighting fixtures are mounted on the walls of building exteriors and used to provide security and illumination around the perimeter. This includes lighting for walkways, alleyways, flagpoles, entrances, exits, mandoors, etc.
Q. Why does my LED wall pack flicker during the day with the dusk to dawn sensor?
Sometimes this can be as simple as a bad photocell sensor, which will switch on and off intermittently. If this happens regardless of ambient lighting, it is more likely that this is actually a bad LED driver and not the sensor itself. Other times, it could be something as simple as a piece of vegetation or something else blocking the proper functioning of the photosensor.
