While traditional lighting systems like HID lamps use fuel sources to generate light, LEDs use semiconductors. LEDs have multiple diodes with separate optics and distribute light evenly across surfaces.
If your main reason for switching to LED technology is to save money, here are three ways you’ll achieve your goal.
The biggest money-saver of LEDs is their low energy consumption. This is the major reason why facility managers and property owners embrace LED lighting. LEDs consume less than half of the electricity conventional lighting systems consume and generate higher-quality light.
Let us give you a short example.
High pressure sodium and metal halide parking lot lights usually have wattages between 250 and 1000. However, they also need ballasts to regulate their voltage and current. Ballasts consume about 15% of the electricity HID lights consume.
The wattage of LED parking lot light fixtures is usually between 65 and 450 and they don’t need ballasts. As soon as traditional lights are replaced with LEDs, energy consumption instantly goes down by up to 75%. Add lighting controls and you can reduce energy consumption by up to 90%. Each LED fixture can save you between $100 and $400 every year. If your parking lot has many lights, you can save thousands of dollars every year and recoup your investment in a very short time.
Maintenance Cost Reduction
One of the best features of LEDs has to be their low-maintenance, which boils down to the way they produce light. As we said earlier, LEDs use semiconductors to generate light, hence their light output decreases gradually over time. Because of the way they are designed, LEDs have a very long lifespan, which means you don’t have to replace the bulbs for years. HID lights, on the other hand, use a fuel source to emit light. As the fuel gets used up, the lights’ functionality decreases.
To service or change parking lot lights, electricians and electrical contractors use bucket trucks or lifts. But since LEDs have such long lifespans, they don’t have to be serviced every now and then. You will save money you would have spent paying electrical contractors to service or change the lights.
You Won’t Need As Many Fixtures
Most parking lot lighting poles usually have 1-2 lighting fixtures while those in busy areas may have up to 4 fixtures. When using traditional lighting systems, you may need more fixtures to ensure your parking lot is well lit at night – as they lose their brightness very fast. However, since LEDs produce higher-quality light, you may only need a few fixtures to produce the same amount of light (lumens) produced by the conventional lights. LEDs also discharge light through a multipoint design which ensures the light is evenly distributed across a surface – in this case a parking lot.
