One of the best things a company can do to save money on their electricity bill is to convert their parking lot lights over to LED.
In some cases we have helped our clients save over 70% on their facilities energy cost and not to mention they create a brighter and safer environment for customers and employees.
There are a few options to going LED with your parking lot lights. Many people choose to retrofit the bulb in the fixture which has it's pro's and con's. In most of the 400W and above wattage applications we choose to go with new LED fixtures designed to manage the thermal dynamics of an LED system. We have found that most parking lot lights are old, the rubber gaskets are worn and allow moisture into the fixture, they tend to be faded/rusted and at the end of the day were not designed for the LED board/retrofit and drivers. The heat generated by a high powered LED module and driver must be managed properly with a heat sink built into the fixture. Old metal halide and high pressure sodium fixtures did not have to address thermal management and therefore were not designed to dissipate heat away from the LED module. In an enclosed environment like a parking lot fixture you can have the life shortened on the system and outright failure due to heat build up.
The coolest thing about going LED is that we are at a point that is very attractive for facility managers and building owners.Switching out the old high pressure sodium or metal halide fixture to a new smart LED fixture is the way to go for most. LED prices have come down significantly, lumen outputs are up significantly, DLC approved LED fixtures have high rebates attached from the power companies and warranties on many of these fixtures are 5 to 10 years!
LED fixtures come with the following features and benefits:
Replacing 250W Metal Halide and High Pressure Sodium
For 80% of all cases, when your fixture is below 20 feet in height, our 60-70W LED Fixture will be more than enough to replace a 250W Metal Halide or High Pressure Sodium fixture. These fixtures produce well over 5,000 lumens. Our customers love the results. This represents a 79% energy savings.
The other option, if your area is under lit or over 20 feet in height, is to consider upgrading to our 75-80W LED Fixture. These LED fixtures produce around 9,000 lumens and realize a savings of 74%. Some vendors believe 9,000 lumens is enough to replace a 400W Metal Halide. So converting to this fixture is definitely an upgrade over the light level that you currently have.
Here are some examples of the energy savings:
60 LED Watts replacing
250 Watts for 12 hrs/day 365 days/yr saving 996 kw/year
* includes ballast draw
75 LED Watts replacing
250 Watts for 12 hrs/day 365 days/yr saving 931 kw/year
* includes ballast draw
Replacing 400W Metal Halide and High Pressure Sodium
We also have some fantastic options when you want to replace your 400W Metal Halide or High Pressure Sodium parking lot fixtures. For most cases, where your fixture is below 30 feet in height our high wattage 120 watt + will be more than enough to replace a 400W Metal Halide or High Pressure Sodium light source. These fixtures produce upwards of 16,000 lumens. They represent as much as a 78% energy savings.
105 LED Watts replacing 400 Watts for 12 hrs/day 365
days/yr saving 1555 kw/year
120 LED Watts replacing 400 Watts for 12 hrs/day 365
days/yr saving 1489 kw/year
What about the rebates?
are available throughout the Country and vary by utility, but with the new DLC program, there is now a difference between DLC Standard and DLC Premium. There are 2 big
differences between the standards, the efficiency and the rebate amounts.
When a fixture or a product receives the DLC Premium rated it means that it has a higher efficiency standard than DLC Standard. So what does that mean for you? It means you fixture will produce more light and consuming less energy. This is real savings and a guaranteed return on your investment in lighting. Since the whole idea of converting over to LED is to save money, efficiency matters.
