EcoLight: Transform Your Space with Smart LEDs

Luminous efficacy is a measure of how nicely a mild source produces seen light. It is the ratio of luminous flux to power, measured in lumens per watt in the Worldwide System of Units (SI). Depending on context, the power will be both the radiant flux of the source's output, or it may be the overall energy (electric power, chemical energy, or others) consumed by the source. Which sense of the time period is intended should normally be inferred from the context, and is sometimes unclear. Not all wavelengths of gentle are equally visible, or equally efficient at stimulating human vision, as a result of spectral sensitivity of the human eye; radiation in the infrared and ultraviolet components of the spectrum is useless for illumination. The luminous efficacy of a supply is the product of how well it converts power to electromagnetic radiation, and the way effectively the emitted radiation is detected by the human eye. Luminous efficacy could be normalized by the maximum attainable luminous efficacy to a dimensionless quantity called luminous effectivity.
