Classification of luminaires

You may heard about the commercial lighting product in Class I or II lamp many times or you saw the label on the lighting product with this classification. But what does it means at all? What’s the difference between them?Let us explain to you here:

Class I luminaire

The protection against electric shock of the luminaire not only depends on the basic insulation, but also includes additional safety measures.Tthe conductive touchable parts are connected to ground. Non-wired luminaires shall have a connection ground for protective ground. We called Basic insulation.

  Class II luminaire

The protection against electric shock of the luminaire not only relies on basic insulation, but also has additional safety measures such as double or reinforced insulation, no protective earthing or measures that depend on the installation conditions.

Class III luminaire

Protection against electric shock relies on a supply voltage that is safe extra low voltage (SELV) and does not produce a luminaire that is higher than the SELV voltage.

  Safety extra low voltage equivalent control gear an electronic control unit for LED modules with isolated and reinforced insulation or double insulation between the output and the power supply and its connecting conductor.
