Light-Emitting Diode (LED) Lighting
An LED is a microchip that emits light. LEDs can produce different colors of light including white light comparable to compact fluorescent (CFL) and incandescent bulbs.
Features that distinguish LEDs from other lighting sources:
- Direct light – LEDs do not require reflectors to point light in the direction it is needed. This makes them ideal for under cabinet and recessed lighting.
- Long lasting – Quality LEDs come with an estimated life of 35,000 to 50,000 hours. In contrast, a typical incandescent bulb will last about 1,000 hours.
- Durable – LEDs can perform well outdoors and in cold temperatures.
- Instant light – LEDs do not require warm-up time to reach full brightness.
- Rapid cycling – LED performance and life are unaffected by frequent on and off.
- Low profile – Many LEDs are compact and can fit into an assortment of lighting fixtures.
- Dimmable – LEDs can be dimmed, but must be designed to do so. Not all are compatible with dimmers designed for incandescent lighting.
- Higher cost – Most LEDs cost significantly more than CFLs and incandescent bulbs.
LEDs can create drama and interest or simply provide quality light to complete a task. They greatly extend lamp life, eliminating frequent replacement, which makes them ideal for hard to reach placement. LEDs can significantly reduce energy consumption without compromising light level.
Buy ENERGY STAR®
When shopping for LEDs:
- Look for the ENERGY STAR® label. ENERGY STAR LEDs must meet performance standards for dimming, rated life, color quality and color temperature.
- Look for lumens. Lumens measure light output. The higher the number, the brighter the light.
- Watts measures energy used. The lower the wattage, the less energy needed to emit light. Watts do not measure brightness or appearance.
