You often ask us how many LED panels will be needed to illuminate a given space. We can most accurately answer this question after we set the dimensions of the room and the interior in specialized software, but in order to have a starting point and orient yourself better, you can use the data from the table below. Note that for an office space, the recommended illuminance is between 300 and 500 lux, with the general opinion that 500 lux is much more than necessary for a pleasant working atmosphere.

The data is achievable at a height of 0.70 m. from the floor (standard height of an office desk) under the following conditions: ceiling height - 2.80m. ; wall color - white.
