Solid-State, Light Emitting Diode (LED) technology offers a myriad of advantages to general lighting applications. The highly efficacious, long life light source can be fully controlled, dimmed, and cycled on and off, revealing tremendous opportunities in energy savings through intelligent and adaptive lighting control scenarios. The controllable nature of LED creates endless possibilities of networking LED luminaires into smarter devices that can better communicate and interact with users and occupants. Emitting less heat results in lower room temperatures and a reduction in HVAC costs. LEDs are also suitable for low ambient temperature environments without start-up issues, such as cold storage, walk-in freezers, and cooler cases. Energy savings and demand reduction are optimized with LED due to being high-efficiency, long life for reduced maintenance, and compatibility with controls.
