Lumen to Lux conversion -- Calculation of luminous intensity and illuminance. NOTE: The conversion from PPFD (µmol m-2 s-1) to Lux varies under different light sources. For a complete discussion please see the reference listed below. in square meters for any light source and press the Calculate button to get the luminous flux in lumens (lm): Lumens is the measurement of total amount of light coming from a light source. Enter the illuminance in lux (lx), select area unit type, enter radius in meters for spherical light source or surface area. Lux (lumen per cubic meter) to Foot-lambert, calculator online, converter Conversion table from Lux (lumen per cubic meter) to Foot-lambert Lux (lumen per cubic meter) Die Definition der Helligkeit einer LED-Beleuchtung oder anderen Lichtquelle in Form des Lichtstroms (die Lichtleistung) einer ist eher ein theoretisches Maß. Der Lichtstrom, der in Lumen (lm) gemessen wird, beschreibt die gesamte Lichtleistung, die von der Lampe in alle Richtungen abgegeben wird. 40 lux to fc = 3.71612 fc. Check the chart for more details. Re: Watt conversion to Lux by Robert Fogt on 03/07/02 at 00:21:19 Lux is unit for measuring the illumination (illuminance) of a surface. Converting between Exposure Value and LUX March 19, 2011 For a recent project, I had to make some rough LUX measurements (LUX is a more international standard for light measurement than candlepower, which is traditionally used in the U.S.) of an environment to help determine what kind of video cameras to use. The amount of light that falls on or through a target is the Lux, which is affected by distance and angle. Lumens – The SI unit of luminous flux, equal to the amount of light emitted per second in a unit solid angle of one steradian from a uniform source of one candela.. Watts – Watts is a combination of Amps and volts.Watts is a measurement of the amount of energy being released. Enter the illuminance in lux (lx), select area unit type, enter radius in meters for spherical light source or surface area. 1 lux to fc = 0.0929 fc.
