The Idea of a Lamp May Be Outdated

The long lifetime of LED light may make the idea of a lamp outdated. Lighting-class LEDs do not fail catastrophically like light bulbs. Instead, they can provide at least 50,000 hours of useful lifetime before they gracefully degrade below 70% of their initial light output (also called lumen maintenance). That's equal to 5.7 years if left on continuously!

However, in most lighting situations, the lights are switched off regularly. This off period can extend the lifetime of the LED well past three decades, as shown in Chart 1 at right. After the years it will take for an LED luminaire to burn out, LED lighting technology will be brighter, more efficient, and probably offer TCO (Total Cost of Ownership) savings over the older LED luminaire.

Light Loss Within the Fixture

Fixture light loss occurs when light rays from the light source strike the fixture housing before hitting the target. Some light is absorbed by the fixture housing, while some is reflected back into the fixture. The efficiency of the fixture is dictated by placement of the light source, the shape of the fixture housing, and materials used in the fixture housing. As the Figure 2 below shows, the directional nature of LED light enables much higher fixture efficiencies than is possible with omni-directional light sources.
