LED wall packs offer a simple, efficient, and long-lasting option for lighting the outdoors near a building. They are especially useful to brighten walkways or parking spaces alongside the building, although depending on the beam angle, a wall pack can send light further out from the wall, potentially to supplement overhead parking lot lighting.
Regardless of how close the beam keeps the light to the building, there is one important term to know. A wall pack labeled as a "cutoff wall pack" (like this one) is one that keeps light at or below the level of the fixture, and this is done to help prevent light pollution.
While there are some locations where more general lighting is needed from a wall pack, so cutoffs are not used, light pollution is becoming a more widely recognized problem, spurring some legislation on the topic. Light pollution doesn't just keep us from seeing most of the stars at night; it can also disturb insect and other animal populations, which means it effects our ecosystem. It can also directly impact human health. Here's an article on the topic.
Cutoff or not, LED wall packs in general are good for the overall environment because they require so much less energy to operate when compared to older lamp technologies. This isn't only because LEDs are more efficient than many technologies, but also because LED light is directional, sending its light only where it's needed rather than relying on reflective fixtures to aim the light.
The LED wall pack pictured here, for instance, uses only 20 watts and is designed to replace a 100 watt metal halide wall pack. You'll also notice that it has a photocell (or photosensor) in the upper left corner. This is another feature you can look for on wall packs to automate your outdoor lighting and make sure the lights are only used when needed. This helps to further reduce energy usage and save you money.
Other points to remember with LED wall packs is that LED technology lasts much longer than metal halide and other lighting technologies, which lowers maintenance costs as well as the effective cost of the fixture itself. On top of that, LEDs provide a better quality of light as measured on the CRI scale.
