Airfal International returns from the Hannover industrial fair satisfied with the results obtained and with a clear winner: the ATEX LED MAX high bay for zone 2, 22. This model stands out for its resistance and versatility since it can be installed as a hood and as an industrial projector.

The Lux or Candela lumens calculator below will help you choose the lighting solution that best meets the specific requirements of your installation. Airfal offers a wide range of high quality and energy efficient LED lights for a wide range of industrial applications and to meet multiple technical requirements.
With this calculator, you can convert a lumens value of a product into a lux value if you know the beam angle and measurement distance. Enter the distance and angle of the beam, then enter a lumens value and click on’Convert to Lux’ or a Lux value and click on’Convert to Lumens’. You can also convert to Candelas.
Iluminance (lux): the iluminance refers to the incidence of the light flux on a surface, per unit of surface
The unit of illumination is the lumen per square metre: lux (lux). A single lux is equal to one lumen per square meter.
Luminous flux (Lm): Total amount of light emitted in all directions by the light source. The lumen (unit lm) gives the total luminous flux of a light source by multiplying the intensity (in candela) by the angular span over which the light is emitted. .
Here are some examples:
Candle 12 lm
Incandescent lamp 60 W 750 lm
LED 1 W 130 lm 130 lm
For example, a 1 candela light source will produce 1 lumen per square meter at a distance of 1 meter.
A lux is equal to one lumen per square meter (lux = lumens/m2).
Luminous intensity / Candela: Candela is the base measurement for describing luminous intensity. It tells you how bright the light source is which shows how far away from an object you can be and while still being able to see it. The unit is the steradian lumen, better known as candela (cd).
The luminous intensity of a candle is 1 candela
Essentially, as the light moves from the transmitter, it disperses into an area. The further away the light has to travel, the more it will be scattered. Therefore, the amount of lux in an area or on a surface can vary depending on the distance travelled by the light and the angle with which it is dispersed.
When the lumens supplied by a given transmitter are the same, light that travels less distance and/or is more narrowly focused will appear brighter because the luxes are concentrated in a smaller area than light that has travelled a greater distance and has been scattered over a larger area.
Beam angle: The beam angle is the radiation angle of a light source. For example, a beam angle of 30 degrees means that the light is shaped like a cone and its edges form a 15 degree angle with the central axis. A change in the radiation angle affects the light intensity (lux) of a light source but not the light flux (Lumens).
LED technology is here to stay with us, at least until other, more sustainable possibilities appear. Let’s briefly review some advantages for our health when using this type of lighting at home. 1. Effects of LED light on biological cycles The wavelength of LED lights determines their colour. There are many studies that associate a […]
