Illuminance

Illuminance, measured in "lux", is prescribed by law for most commercial applications. Different lux values apply for different areas of activity. The values stated refer to the amount of light reaching the ground. 

Typical work for woodworking companies:

Sanding, carpentry, wood selection, inlay work: 750 lux  

Work on machines (grinding, turning, milling, cutting, planing): 500 Lux  

Quality control: 1000 Lux  

Gluing, assembly: 300 Lux

Colour rendering index

Especially in craft businesses it is important that the light reflects the surrounding colours as naturally as possible. The CRI (= color rendering index) provides information about the color rendering of light. This should be >80 for joineries and woodworking companies.

Blinding

Luminaires used in workshops must under no circumstances be allowed to dazzle, as this is not only perceived as annoying but can also lead to massive hazards, especially when working with machines. Glare can be prevented by specially developed optics, but the mounting height and angle are also important prerequisites for safe working. In order to identify which luminaires cause more or less glare, the degree of glare is measured in the so-called UGR value.

Water and dust protection

Not only dust protection, but also protection against water is of considerable relevance for joineries and other woodworking companies. 

Both are represented in the IP protection of the luminaire. Protection against foreign bodies and contact is the first digit (in this case ≥5), the second digit refers to protection against moisture.
