A Source of Projects for Electricians: LED Parking Lot Lights
Presented by LED Corporations
Electricians nationwide are finding significant LED projects in parking lots. As typical high intensity discharge (HID) bulbs and fixtures become increasingly inefficient, replacing them with light-emitting diodes (LEDs) is an easy sell to parking lot owners for several reasons.
First, LED lighting dramatically improves appearance and security. Because the color temperature (measured in Kelvins) can be customized, property owners can choose their preference. Typical choices include:
- 2700K-3200 kelvin – LEDs emit a warm reddish glow similar to high pressure sodium (HPS) lighting.
- 4000K- 5000 kelvin – produces a white light that replicates daylight
- 6000 kelvin + – provides and intense platinum white as you would find in a museum, with high Kelvin ranges emitting a blue cast.
Another advantage with LED’s for parking lot lights is that the light can be targeted. There is no spill over, which means no lumen’s will be wasted. LEDs focus light downward where the light needs to be with controlled beam angles, unlike conventional bulbs that indiscriminately blast light 360-degrees. By putting the light only where it’s needed, you save energy and brighten your property without annoying neighbors.
Energy Savings Explained
LED has several advantages over HID, but perhaps the largest is energy savings. LED’s are able to produce the same amount of light, or lumen’s on the ground as HIDs with 70% to 80% less energy use. For example, a 300 watt LED fixture produces light equivalent to a 1000 watt HID light. And the ratio is only getting better; as of this writing we’re weeks away from LED fixtures equivalent to 1000W HID output using just 200- 225 watts of energy.
To illustrate the savings, perhaps this simple formula will help. A 1000 watt bulb burns one (1) kilowatt per hour. On average, your utility charges 12-cents per kilowatt hour, so the 1000 watt bulb costs 12-cents per hour of operation. That may not sound like a lot, but consider this: an auto dealership can have fifty 1000 watt bulbs burning. This is costing the owner $6.00 per hour. Still sound like chicken feed? Consider that those lights are on from dusk to dawn, or on average eleven (11) hours per day. That’s $66.00. Ho-hum. Price of doing business, right? But multiply that by 365 days and you get a whopping $24,090 energy bill.
Conversely, a 300 watt LED fixture can operate for over three hours without burning even one complete kilowatt! Using the same formula above, it’s easy to calculate the savings. The 300 watt LED costs 3.6 cents per hour to operate. If your client has 50 fixtures as in the example above, he’ll pay about $1.80 per hour of operation. Multiply that by eleven hours of operation from dusk to dawn and the cost is $19.80 (instead of $66). Over the year cost? $7.227 instead of $24,090. That’s a $16,863 savings year after year for the next 20 years, not to mention the reduced pollution of disposed bulbs and stress on our environment.
On top of this, as LEDs are solid state instruments with no moving parts or filaments, they’re warrantied by most legitimate manufacturers for five-to-10 years. Most products manufactured in the US carry a 10-Year warranty. This means significant savings, if not outright elimination of maintenance costs.
This information when presented to your clients should go a long way toward helping you secure profitable projects, and it truly is a WIN/WIN proposition.
