The takeaway here is that LED lighting offers much better luminous efficacy than traditional incandescent lighting and CFL lighting. In addition to the better luminous efficacy. LED lighting also has a longer lifespan. This extended lifespan translates to lower maintenance and replacement costs when looked at a 3 to 5-year period.

It gave us a new and simpler way to get high-quality lighting in our aisles without any upfront costs or hassle. This is important to understand, since many types of fixtures trap the emitted light inside the fixture. Many downlights, wall packs, ceiling troffers, and other fixtures have low efficiency, requiring much more lumens from the lamp than actually makes it outside the fixture to provide useful light output. Efficacy is calculated by dividing the fixture lumens by the total fixture wattage consumed.
This is NOT good efficacy. Most modern LED fixtures are over lumens per watt efficacy with some exceeding lumens per watt! What are the power conversion efficiency, external quantum efficiency and the luminous efficacy?
Answer from the author :. Luminous efficacy: 0. Remark: despite the good quantum efficiency, the luminous efficacy is low due to the poor responsivity of the human eye at nm.

The more common definition is the luminous flux divided by the electrical power consumption of a light source. The same luminous flux could be generated with a lamp based on light emitting diodes LEDs with a power consumption well below 10 W, since it is much more efficacious. Dependence of Efficacy on Temperature, Dimming and Aging The luminous efficacy of some light sources is temperature-dependent.
