What exactly is a wall pack light? Everything you should know

led lighting

Outdoor lighting that is typically put on the outside facing walls of buildings is referred to as wall pack lights or outside building lights. This form of outdoor lighting is often used to illuminate ground areas frequented by automobiles and people. They also provide an additional degree of protection for property owners. Multiple lamps set on a single structure or wall are not unusual, with the fixture spacing chosen to give uniform illumination around the grounds. The images below show typical wall pack lighting placed on an outside wall.

Most present industrial and commercial light fixtures, such as wall packs lights and building lights, use high-intensity charge (hid) bulbs such as metal halide (MH), high-pressure sodium, and, in the case of extremely ancient fixtures, mercury vapor lamps.

What are the advantages of using led wall pack lighting? Why should you choose led wall pack lights instead of traditional lighting solutions?

A sodium vapor lamp is most frequently used in an outdoor wall pack light. Sodium vapor lamps are often quite a deep yellow (or orange) in color. In return for reasonably excellent energy economy for a legacy bulb technology, low-pressure sodium vapor lamps emit a monochromatic emission that tends to portray color extremely badly. Interior alternatives for wall pack lighting include traditional incandescent lights, however, mercury vapor bulbs are most often used.

While each of these technologies has advantages, industrial led lighting exceeds all traditional options in significant ways. Let’s look at some of the factors to consider when considering if a led retrofit is right for your wall pack lighting.

  • Sodium vapor vs. Industrial led wall pack lighting:

If you’ve ever wandered around a parking lot or a building’s exterior at night and observed a rich yellow glow, the lights you’re looking at are most likely sodium vapor. Low-pressure sodium lights provide a very deep yellow, monochromatic light, and high-pressure sodium lights produce a little whiter (but still mostly yellow) light. Prior to the advancements in LEDs, these lights were the most efficient alternative on the market. MH lights are often used in sports and warehouse/industrial settings (as well as any setting where large, high spaces need to be illuminated).

The advantages of MH lights include good color rendering and relatively high foot-candle levels (as opposed to other types of conventional bulbs). Some of its significant disadvantages include the fact that they take a long time to warm up (sometimes 15-30 minutes) and are costly to maintain. Their failure features include flashing on and off and energy waste due to heat. Learn more about the differences between led and metal halide lighting.


  • High-bay led lighting vs. High-pressure sodium (hps) lighting:

HPS lamps are often utilized in warehouses, industrial, commercial, and recreational locations where high bay illumination is required. They have modest selling prices, good energy efficiency (low running expenses), and generally lengthy lifespans. Although hps lighting technology maintains these benefits over most conventional bulbs, it falls short on all three criteria when compared to led high bay lighting. Hps bulbs have the worst color rendering on the market and need a warm-up time. Learn more about led vs. High and low-pressure sodium.

What are the three most significant advantages of employing led lighting technology in all applications?

It’s no secret that led lighting technology has significantly outperformed traditional lighting in many ways. In addition to the points raised above, there are three basic advantages of using led lighting that apply to all lighting situations, not only high bay.

  • Less maintenance is required.

Led lights, as previously stated, have a lifetime that is four to forty times that of traditional bulbs. This implies fewer replacements for burned-out bulbs. Led lighting technology also produces light differently from traditional fuel and filament lighting since it uses a diode rather than a filament (learn more in this blog). This implies fewer moving parts to fail and, as a result, fewer repairs or replacements. When it comes to industrial lighting or warehouse lighting, maintenance is very critical.

Because wall pack lighting often has greater mounting heights, replacing a bulb necessitates the use of a ladder and, in some circumstances, specialized hydraulic lifts. All of this adds up in maintenance, labor, and equipment expenses. Because of the long lifetime of industrial led lighting, fixtures must be replaced significantly less often, resulting in cost savings for your business.

  • Better lighting quality.

When it comes to color rendering index (cri), correlated color temperature (CT), and foot candles, led lighting for wall pack lights often outperforms most other bulbs.

The color rendering index (cri) of light is a measurement of its ability to disclose the true color of things when compared to an ideal light source (natural light). In layman’s words, cct characterizes the “glow” emitted by a bulb – is it warm (reddish) or chilly (bluish white)? Foot candles compare the quantity of light that comes from a source to the amount of light that hits the intended surface; they are essentially a measure of efficiency. Led lights outperform in all three categories.

  • Install just where it is required

The primary idea of illumination is to employ as few lighting fixtures as possible to create enough illumination and a pleasant lighting experience. Wall pack lights are intended to increase pedestrian visibility while also ensuring security around structures.

There is no need to put wall pack lights in areas where there is no pedestrian movement or where there are no security concerns. Otherwise, it will be a waste of time and effort. It has the potential to exacerbate lighting pollution. Pay special attention to areas that need lightings, such as the pathway, entrance, and departure. The distance between wall pack lights is also important. If the fixtures are too near together, the illumination will be partially or completely coincided. A proper installation distance helps to provide homogeneous and effective illumination.

  • Controls – Conserve energy and lower your power bill

The most effective approach to using a wall pack light is with appropriate settings and light levels. Consider the individual demands of applications while picking controls. Applications with limited or occasional activity, such as entry, walkway, and exit, should be used with controls to conserve energy and reduce power bills. Intelligent control may significantly reduce energy consumption in areas with security concerns or as the demarcation of the building’s perimeter. However, the form of control must be carefully chosen.

Consider photo sensors, which can automatically turn on and off numerous fixtures with comparable control demands depending on ambient light levels. Applications that are not tied to an entry or pathway are better suited for occupancy sensor installation. When occupancy sensors are activated, lighting fixtures switch on automatically and turn off within a few minutes after all inhabitants leave the detecting area. Adding controls is a more efficient method to utilize wall pack lighting since it reduces energy usage and electricity bills.
