How much money can I expect to save if I convert to LED? LED bulbs are more energy efficient than both High Intensity Discharge (HID) and Compact Fluorescent (CFL) lights. The amount of money you can save on energy costs will vary depending on the type of lighting you currently have. For example, a 4 lamp T5 fluorescent bay light can cost $126 to run per year vs. $66 for a comparable 150 watt LED bay light. 200 watt HID flood light can cost $128 per year, while a comparable 84 watt LED flood light costs only $37. When you have as many lights as many industrial or commercial buildings do, you can see how that savings really adds up.
In addition to energy savings, maintenance is also a major cost savings with commercial LED lights. HID bulbs are rather fragile, while LED’s are much more durable. Also, the average lifespan of a HID light is around 30,000 hours and a CFL lifespan is around 60,000. LED’s on the other hand, have a lifespan that can be more than 100,000. That certainly means less maintenance and fewer replacement lights to buy per year.
LED lights also have the advantage of being dimmable and more easily controllable than HID. That allows you to set your lighting to use as little energy as possible.
There is a higher up-front cost for LED vs. CFL/HID, but that is easily offset by the energy, lifespan and maintenance costs.
Where can I find out more about any tax credits or rebates available? Energy.gov has this handy tool to help you find out if there are any rebates available in your area. You can filter for location, commercial or industrial eligibility and savings category.
What other advantages are there for using LED in commercial and industrial applications? One advantage of LED lights is that they don’t have the “warm up” time you see with CFL and HID lighting.
Additionally, there are more color temperatures available for LED lights (2700-6500 Kelvin) than for HID (3000-5000 Kelvin).
Finally, LED lights have many more options for lighting distribution patterns than CFL or HID. That allows you to configure a lighting design plan that puts the light where you want it, which is especially important for working conditions and employee safety.
