The level of illumination required in the industry depends on:

The use of luxmeters makes it possible to obtain an optimal level of illumination.

Improved level of illuminance and uniformity by lowering installed power.

In this case, a higher level of illumination measured in LUX will be required.

the average degree of illuminance (parabola) in lx on the vertical axis on the left

What’s more, they are adapted to low-light vision.

155 (1) The level of lighting at any place in an area must not be less than one third of the average level of lighting prescribed by this Part for the area.

In particular, the average lighting level to be maintained depends on the use and people.

For this reason, the level of illumination provided by emergency lights should ideally match the usual light levels in the building.

The minimum illuminance level for working in good conditions is 300 lux.

Each activity requires a specific level of illumination in the area where the activity takes place.

In particular, the average lighting level to be maintained depends on the use and people.

Fixed lighting yielding a level of illumination of at least 50 lux shall be installed:

Following the European standard EN 12464-1, the value of minimally 500 lx is required for common administrative activities.

A great reduction of the power is accomplished, maintaining the same illumination level (Lux).
