LED Wall Packs: How to Calculate Return On Investment (ROI)

LED wall packs, area lighting fixtures that mount to the side of buildings, are an efficient way to light a parking lot. Although wall pack landscape, come in a variety of shapes, wattages, and beam angles, one thing they have in common is their consumption of electrical energy.

Wall pack light’s, have depended heavily upon high wattage metal halide bulbs to deliver lumens. However, the advent of LED lighting, with its flexibility in housing options, wattages, and beam angles, is rapidly transforming the wall pack landscape.

Increasingly, when weighing the pros and cons of LED commercial wall pack versus their High-Intensity Discharge (HID) alternatives, the only advantage is that the initial materials costs of HID bulbs is less expensive than LEDs. However, that expensive is quickly eclipsed by maintenance and energy costs.


A rule of thumb regarding LEDs is that you can use a quarter of the wattage of HID bulbs to replicate the same amount of lumens.

Consider a shopping mall with fourteen (14) 400 Watt Metal Halide fixtures. These fixtures burn approximately 5.6 kilowatts per operating hour. If the mall owner pays the national average of 12-cents per kilowatt hour (KwH), his energy expense is 67-cents per hour. If his wall packs are burning from dusk to dawn or 11-hours per day, 365 days per year, the mall owner is paying close to $2,700 in energy costs. And then, with the HID bulb, the mall owner must contend with light loss and the expense of replacing bulbs and ballasts when they expire, typically within three years.

Conversely, the energy expenditure of an equivalent LED Wall Pack will be much less:

Fourteen (14) 120 Watt LED Wall Pack fixtures will burn just 1.68 Kilowatts per operating hour. At eleven hours per day, 365 days per year, the mall owner’s energy expense is just $809.42 per year. That’s a savings $1,888.66 per year. Also, as the LED wall pack has a five-year warranty and will likely last for 10 or more years, the mall owner saves in maintenance costs as well.


Added benefits are to the community; our landfills are spared the waste of yet more mercury-laced bulbs, and our utilities will pause before building more nuclear power plants to accommodate the ever-increasing energy demands.

A rough ROI for the mall owner is less than three years, which means at least 7 years of complete money-in-his-pocket savings. It would appear to be as close to a no-brainer situation as one can get.

As an added benefit, the 120-watt wall pack will produce even more light than the 400-watt metal halide with less light loss over time.
