Targeted lighting of the usable area. A horizontal light-emitting surface, appropriately selected light distribution and a low light source height reduce the long-range effect. Provide louvres if additional lighting is required.
Avoid overexposure
Avoid excessive lighting and do not exceed the required illuminance levels. Ensure that the luminaire control gear includes control options (e.g. dimming, constant luminous flux control (CLO)).
Light colour: Amber or warm white
Avoid short-wavelength radiation below 490 nanometres. Amber LEDs or warm white LEDs (colour temperature max. 3000 Kelvin) are suitable light sources.
