2013-02-23 Convert lumens to watts. Old light sources such as incandescent bulbs or halogen lamps were easy to choose. Here the wattage was the most important indicator for the brightness.If a 60W bulb fails, it could be simply replaced by a new 60W bulb. Lux. Lux (unit lx) is a measure of illumination of a surface. Light meters often measure lux values (or footcandles, but these are directly related: one footcandle is 10.764 lx). Formally, lux is a derived unit from lumen, which is a derived unit from candela.

75, 1 100. 100, 1 600. >150, 2 600 När du ska välja lampa så titta i första hand på hur mycket ljus lampan ger, detta kallas ljusflöde och visas i lumen vilket ofta förkortas lm. I tabellen nedan kan du Här har vi en som säger att 5630 ger 800-900 lm/m. på 48 kvadratmeter borde ge uppemot 800 lux om verkningsgraden är 80 lumen/Watt. Så långt jag fattat handlar det endast om ljusbilden.

Lux är lumen per kvadratmeter, en lux är definierad som en lumen per kvadratmeter. Hur många lux ska man ha? Ljus är viktigt för välbefinnandet och för att kunna utföra ett arbete eller studera utan att bli trött, därför finns det rekommendationer på hur mycket ljus man ska ha i vissa typer av lokaler.

Relationship between Lumens & Lux. One lux (1 lux) is defined as being equivalent to one lumen spread over an area of one square metre. To put it another way: A specification in lux tells you how many Lumens (total light output) you need given the measured area you are trying to illuminate.

When calculating the illuminated area at a certain distance, you will have to make sure that the calculation is made with same distance for the entire light beam, since the light intensity (lux) depends on the distance. It means that the illuminance in lux is calculated by multiplying the luminous flux in lumens by 10.76391 and the result divided by the surface area in square feet. Ev (lx) = 10.76391 x фv (lm) / (4.∏.r (ft) 2).

Lumen: A measure of light given off by a source. One lumen equals the amount of light emitted by one candle that falls on one square foot of surface located one foot from the candle. Footcandle: A measure of radiant light from a standard candle that falls on one square foot of surface area at a distance of one foot. LUX: Lumens to Lux calculator It is a conversion calculator that is used to convert the luminous flux in lumens (lm) to the illuminance in lux (lx). It has three text fields and two controls that perform different functions of the calculator. The initial step is to enter the luminous flux in lumens and then select the unit type of the area. The lumen (symbol: lm) is the SI derived unit of luminous flux, a measure of the total quantity of visible light emitted by a source per unit of time.

Halogen bulbs will require at least 45 Watts to reach this amount of Lumens needed. Switching over to CFL bulbs, the wattage is much lower and only uses 13 watts to reach 800 Lumens.

Step 2. Understand Lumens. A lumen is a measure of visible light energy. More lumens equals a brighter light. All lighting manufacturers are starting to tell us how many lumens are produced for each of their lighting products. We see these lumen numbers on the Lighting Facts labels found on all new LED bulb packages.
