candela disc illuminance lambert light LM lumen luminous intensity lux optic atrophy photometry reflectance retinal illuminance SI unit visible spectrum			These LED lights offer lower energy consumption, cool touch, clear light with no infrared or ultraviolet radiation and a long life of up to 50,000 operative hours with 70% of the luminous flux guaranteed, according to the company. LED lighting by Wood & Wood Products Unlike radiant flux, which measures the total amount of light energy put out by a light source, luminous flux measures the amount of light that can be perceived by the human eye. Lumens and LEDs That Use Them Explained by Ben Anton / Home based business community In order to improve the situation, NIST has investigated the technical problems and is developing standard LEDs and recommended measurement methods for luminous intensity, total luminous flux, and color (chromaticity and dominant wavelength).
