How to Amplify Your Savings When You Convert to LED Technology

One of the benefits of LED technology that we frequently talk about here at The Lighting Center is cost savings. But did you know that you can save even more money by adding a few add-ons?

How Much Will You Save By Switching to LED?

If you currently use 400-watt high pressure sodium or metal halide flood lights in your exterior and you decide to retrofit the fixtures with the 100-watt LED retrofits sold by The Lighting Center and you switch on the lights only at night (for 12 hours), you will save a lot of money for every HID light you replace with a LED light, depending on your electricity cost.

Cost savings realized after replacing a 400-watt HID light with a 100-watt LED light that operates for 12 hours a day (365 days a year): 1577 kw/year (including ballast draw)

Cost per kw/h	Savings per year
.06	$95
.08	$126
.10	$158
.12	$189
.14	$221
.16	$252
.18	$284
.20	$315

 

By looking at the above table, you can see that you’ll save $315 per fixture every year if your electricity cost is .20 kw/hr.

Boost Savings Further by Adding Lighting Controls

After you convert to LED technology, you can save even more money by getting lighting controls. LEDs work with a variety of lighting controls, unlike HID lights and most types of fluorescent lights. For example, HID lights cannot work with motion sensors – which switch lights on and off automatically if they sense any activity – because they have a long warm up time.

When motion sensors are combined with dimmers (0-10V), they can turn on lights only when movement is detected and dim lights if there’s no activity. Some areas in buildings don’t have a lot of activity so the lights do not need to run at full power all the time. You can set them to run at 50% power and at full power when any movement is detected.

Cost savings realized after replacing a 400-watt HID light with a 50-watt LED light that operates for 12 hours a day (365 days a year): 1577 kw/year (includes ballast draw)

Cost per kw/h	Savings per year
.06	$190
.08	$252
.10	$316
.12	$378
.14	$442
.16	$504
.18	$568
.20	$630

 

As you can see, you can save a lot more money by pairing lighting controls with LED lighting. But you must make sure you use the right controls for the settings.
