Wat is de lichtstroom op een oppervlak van 4 vierkante meter en een verlichtingssterkte. Uit de tabel hieronder kun je aflezen hoeveel lumen een nieuwe lamp ongeveer moet hebben als je er een bepaalde gloeilamp door wilt vervangen. Lighting designers should be engaged for guidance whenever possible. Dus de lichtstroom V in lumen (lm) is gelijk aan de verlichtingssterkte E v in lux (lx) maal 4 keer pi maal de vierkante bolstraal r in meters (m): V (lm) E v (lx) × 4 r 2.

IES files are used daily to bring professional results to homes and business environments. The Illuminating Engineering Society (IES) created a system to provide lighting designers with a method to create designs based upon the unique photometric signature of each light. Don’t be sold just on watts! High Lumens per Watt is the specification that will save you energy. It is no longer relevant to talk about the “wattage” of LEDs in context of the brightness of the luminaire. Lux wordt gebruikt om de lichtsterkte in een bepaald gebied te meten één lux is gelijk aan één lumen per vierkante meter. Bij led verlichting is deze waarde veel hoger omdat ze minder stroom nodig hebben om een bepaalde lichtsterkte op te wekken.

The “efficacy” of an LED system is a calculation of how many Lumens are produced by a single Watt of energy input. Dit wordt de Lumen/Watt verhouding (Lm/W) genoemd.

Lux meters can be purchased cheaply to allow measurement of light on your working surfaces, but the cost and complexity of accurately measuring Lumens is far greater. Find the result using the formula: lux lumens × area 323 lx × 20 m² 6,460 lm. For a studio, the recommended value is 323 lx. 25 - 28 watt LED bulbs can produce nearly 3000 lumens, which is equivalent to a 150-watt incandescent bulb. LED bulbs with 4 - 6 watt energy consumption can already produce 400 - 500 lumens, which is equivalent to a 40-watt incandescent bulb. “Lumens” is the total amount of light produced by the lamp or light fitting, while we use “Lux” as a measure to know how much of that light is arriving on to a particular point of a surface. To calculate this result: Compute the area of the room: area 4 m × 5 m 20 m². The illuminance Ev in lux (lx) is equal to 10. The energy consumption of the LED bulbs is very low.
