Light intensity calculator

Please, specify the type of the room, for which you wish to design the lighting!
– 5 simple steps –
Please, specify the surface of the room in m2!
Please, specify the type of the luminous source you wish to use in the room!
Please, specify the power of the luminous source you wish to use (W)!
Please, specify the luminous flux rate of the luminous source you wish to use (Lumen)!
According to the data that you have selected and entered:

Thank you for your opinion!

The illumination of rooms with different functions requires different light intensity, the necessary lighting will be calculated, at your option, either on the basis of an average or a recommended rate. For the average height of the rooms 2.6 m is considered by the calculator. The most frequent standard rates (lux) for the indoor artificial lighting will be calculated by the calculator in accordance with the norm MSZ 6240.

Correction coefficients considered by the calculator:

  • Ageing:

Ageing must be taken into consideration already for the design of lighting. The initial luminous flux of the lighting equipment will be gradually diminished by the reduction of the luminous flux and the lamp becoming dirty. This should be corrected by the ageing coefficient. The ageing is specified for the whole expected lifetime of the luminous source.

  • Reflection of light:

The correction of the reflection by the walls is very complex due to the surface roughness, the built-in furniture, the form and color of the machines.
