Start with 0.55 hexagons per m², then add 50% as soon as the height exceeds 3 m. For 200 m² under 5 m, that's about 165 hexagons — height is the determining factor, not surface area alone.

Because light diminishes with distance. At 5 m, a frame dimensioned for 2.50 m gives the impression of gloom on the ground, even if the ceiling itself appears well lit.

Always on the supporting structure, never in the sheet metal or in a suspended plate. The fastening material depends on the support: solid concrete, hollow concrete, steel deck, and wooden framework do not require the same anchors.

This is an option when the work area is clearly identified: moving the source 1.50 m closer really improves comfort on the ground. But we always maintain the headroom required for vehicles and machinery to pass.

This should be checked before purchase. A large frame represents a power that may exceed what the existing lighting circuit can handle. In a professional setting, any work on the electrical panel should be carried carried out by an electrician.

It's important to think about this during the design phase. A simple annual cleaning requires a lift or scaffolding: it's better to plan for accessible bays than to discover the problem after installation.

Yes. Any premises open to the public must have independent emergency lighting that takes over in the event of a power outage: an LED array can never serve this purpose. The applicable regulations depend on the type of establishment — have them confirmed by a professional.

An uninsulated shed experiences significant temperature variations and a lot of dust. Observe the indicated mounting distances, and provide an appropriate IP rating in washing areas or areas open to the elements.
