Perfect Light for Locksmith's Shops

Illuminance

measured in lux

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.

Tool, gauge and fixture construction, precision and micromechanics: 1000 Lux, CRI 80 

Very fine assembly work: 750 Lux, CRI 80 

Electroplating; welding: 300 Lux, CRI 80 

Forging; casting and melting shops, emptying stations, machine moulding shop: 200 Lux, CRI 60 

Machine work: 300 – 500 Lux, CRI 60 

Marking, control: 300 Lux, CRI 60 

Wire and tube drawing, cold forming: 750 Lux, CRI 60 

Sheet metal processing: 200 – 300 Lux, CRI 60 

Production of tools and cutlery: 300 Lux, CRI 60

Protection against dust and water

IP Protection

The protection factor of luminaires is of great importance in metalworking companies. Due to the occurrence of dust, sparks and moisture, the luminaires should be equipped with an IP protection of ≥ IP54 so that dust and splash water cannot harm them.

Glare

UGR = Unified Glare Rating

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. 

Color Rendering Index

CRI 

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 index should be >60 when working in locksmitheries and metalworking companies.
