When you start researching what kind of lights are in parking lots, you will find that many locations around the country still use conventional area lighting. Parking lot lighting is something the majority of the population encounter on a regular basis. It is used in shopping centers, warehouses, schools, distribution center and office complex parking lots.
When it comes to conventional parking lot lighting, most venues use either high-pressure sodium lamps, high-intensity discharge (HID) lamps or mercury vapor lamps. There are three main drawbacks of these conventional lighting options: frequent maintenance costs, sub-par lighting performance, and high energy running costs. Let’s discuss those drawbacks in more detail:
High Energy Costs
Old-style high-intensity discharge lamps used in parking lots can use between 100 and 1000 watts each. When the size of the area requiring illumination is large, you can see how energy usage rates for lighting can really add up. A typically 1000 watt conventional area light fixture can use over $525’s worth of electricity each year. The reason conventional bulbs use so much energy is that they give off a lot of heat.
High Maintenance Costs
The maintenance of conventional exterior parking lot lighting can be very high. Since the lamps are mounted onto poles that are higher than 15 feet, so a bucket truck needs to be called out every time a ballast or lamp needs to be changed. Hiring such a truck and contractor to carry out the routine maintenance work can be costly. The maintenance expenses mount up over time. In some areas of the country, it can cost over $350 per light per year for maintenance.
Sub-Par Lighting Performance
Despite the high energy usage of conventional HID flood lamps, they can experience accelerated lumen degradation over time. This means that light output from the lamps gets worse over time. The only good thing about HID lamps is that they do produce white light. High-pressure sodium lamps, meanwhile, are less susceptible to lumen degradation over time, but they tend to give off an orange light and they still use lots of energy.
LED Lighting Solutions
The good news is that LED lighting technology is now available for parking lot lighting and area flood lighting. This type of technology can reduce energy costs massively and provide much better illumination to an area. Furthermore, once installed, LED lighting does not require much maintenance. You can learn more about the latest parking lot lighting from any good LED solution supplies website.
An LED parking lot fixture can produce 7000 to 66,00 lumens. They can be used to replace 1000W metal halide models and use up to 70% less energy. Another good thing about LED area lights is that they can be programmed to automatically dim when no motion is detected in the surrounding area. A dimmed light will use a lot less electricity and dimming the light won’t negatively impact the LED’s lifespan. When used for 12 hours each night, an average LED fixture will provide maintenance-free bright lighting for years.
