How LED Parking Lot Lights Save Energy

Posted on

Parking lot lights such as pole and floodlights require a lot of money to operate.

The high cost is because they will be on most of the night, which has earned them the name, always-on lighting.

However, LED parking lot lights can help to reduce this cost substantially, and as such, they are the best types of lights for illuminating large spaces for a long time.

These lights can be beneficial to both manufacturers, facility managers, and building owners in terms of reducing maintenance costs, saving energy, and improving environmental sustainability.

Bright LED lights for parking lot have also become an essential part of our landscape since they affect the places we visit or work.

While they illuminate the space to provide clear visibility, they also make employees, customers, visitors, and passers-by feel safe.

That being the case, there are several ways LED parking lot lights have been able to save energy for buildings that have adopted its use.

LED Parking Lot Lights

LED parking lot lights are available in a variety of fixtures, including area lights for outdoor parking lots and wraparound light fixtures for indoor parking lots.

They can be used in the parking lots of factories, warehouses, parks, hospitals, apartment buildings, etc. for branding, site aesthetics, and to ensure customer safety.

These lights are widely known to be the most energy-efficient bulbs in comparison to traditional lighting technology.

They save energy consumption by 75% in commercial properties that use them, which has brought about the prevalence of LED technology over inefficient outdoor lighting systems.

LED parking lot lights provide illumination for vehicles and pedestrians, and they are available in different fixture shapes, sizes, and designs such as concrete, aluminum, fiberglass, and wood.

This diversification enables them to be classified as lighting for parking garages or canopies.

LEDs in themselves, are semiconductors that emit visible light as a result of the passage of electric current.

How LED Lights Save Energy

Unarguably, LED parking lot lights can save energy, and that can be backed by several facts.

The Office of Energy Efficiency & Renewable Energy, for instance, states that LEDs reduce parking lot energy use by over 50% in comparison to traditional or conventional lights.

The U.S. Department of Energy also revealed that organizations in 2014 which had adopted efficient lighting in their parking lots were able to save energy use by 90%.

Asides from reducing energy cost, LEDs also lower maintenance costs for businesses.

In the case of the latter, the longer lifespan of an LED system helps to defer the need for maintenance.

Now, let’s take a look at each:

1. LEDs’ Less Power Wattage:

LED parking lot lighting has a wattage between 40 watts to 600 watts.

However, the HID parking lot lights’ wattage goes as high as 400 watts to 1000 watts.

Metal halide and High-pressure sodium parking lot lights also feature wattages between 250 watts and 1000 watts.

Coupled with this high energy consumption, they still need their voltage and current to be regulated using ballasts.

Ballasts, in this case, consume 15% of the energy that will be used by HID lights.

Over the years, countries have also found a need for energy-efficient lighting given that the E.U. began the ban of incandescents in 2009 and Canada stopped the importation of incandescent bulbs with higher wattage in 2014.

The U.S. also took a stance to set up energy efficiency guidelines in 2007.

2. LEDs Provide Higher Quality Light:

LEDs tend to consume less than half the electrical energy used by conventional lighting systems, yet they still generate higher-quality light

While an LED’s wattage is lower, these bulbs are still able to provide bright enough light for the spaces they illuminate.

At the same time, they use less amount of energy in comparison to High-intensity discharge (HID) lamps that were once a popular type of lights.

What this means that migration from HID to LED could help a facility reap a 40%-60% reduction in its energy consumption.

3. LEDs Ability to Save Electrical Cost:

The dollar value savings achieved through the use of LEDs would be close to $300 if not more for each light fixture in a facility, yearly.

If the parking lot is large and more LEDs are used, the electricity costs can be significantly reduced as well.

Thus, these benefits have been one of the main drivers for business owners who switch to commercial parking lot lighting fixtures.

The Department of Energy estimated in April 2014 that building owners spend over $6 billion a year to light their parking lots and garages.

When you come to think of how much can be saved from the figure above, it’s quite a lot.

Similarly, the U.S. Department of Energy said if LEDs were rapidly adopted in the U.S., it could save about $265 billion in energy costs over the next 20 years.

There will also be no need for 40 power plants in the next two decades.

4. Luminous Efficiency (Efficacy) of the LEDs

Luminous efficacy is the ratio of the light output produced (luminous flux) by a light source to the power it consumes.

It considers the energy consumed and the heat lost by the light source, and in this case, LEDs.

A LEDs’ luminous efficacy helps to determine how economical it will be, and a higher value means its better.

The latter is the case because the bulb will tend to use less energy to produce more light.

It takes it one step further to reduce the energy cost for a facility and as such when choosing an LED for interior and exterior lighting, significant consideration has to be given to the luminous efficacy.

Conclusion

Energy-saving outdoor lighting is essential for customers and employees to navigate their way in and out of buildings in the evenings and at night while also keeping crime and car accidents at bay.

The same goes for the security cameras that will need to monitor the state of things which can only be made possible if the area is well illuminated.

These benefits and many more are what led parking lot lighting can provide, and if you’re a manufacturer or business owner, serious thought should be given to using LED light fixtures as a replacement in your facility.

It’s even better to know that on a yearly basis, you can reduce the electricity cost of providing sufficient light for your parking space hence, what’s saved can be put to better use.

That being the case, you can still maintain strict lighting standards while at the same time ensuring that you do not break your bank thanks to the energy efficiency of led parking lot lighting.
