Advances in Technology
Lighting is essential for all businesses. It is also a major energy expense - accounting for 30 percent to 60 percent of annual electric costs for businesses.
High-intensity discharge (HID) sources are the most common lamps used outdoors. As this type of lighting is not suitable to dimming or frequent on-off switching, these lights are typically left on all night, even when the parking lot or garage is mostly or completely empty.
As technology continues to advance, there are new energy efficiency lighting options that can save energy and money, both indoors and out.
