LIGHT COLOUR SELECTABLE

Luminaires with the designation "CCT Dip" allow you to
change the light colour via a small dip switch [usually in the
steps 3000K / 4000K / 5000K]. With their high application
flexibility, CCT Dip luminaires offer customers who are still
unsure about the light colour an enormous decision-making
aid - and incidentally reduce your stock requirements.

The colour temperature [light colour] is specified in Kelvin [K]
and determines how the respective light is perceived.
WW = Warm white light 2,300 K to 3,300 K [high red component].
NW = Neutral white light 3,300 K to 5,300 K
CW = Cool white / daylight white light 5,300 K to 8,000 K [high blue content]

Ra COLOUR RENDERING INDEX RA

The colour rendering index Ra is the measure of the corres- Standard values:
pondence of the perceived light colour between an existing Incandescent bulb, halogen lamps up to Ra 100
lighting situation and a reference light source. The smaller LED lamps Ra 75-95
the deviation, the better the colour rendition. Compact fluorescent and energy-saving lamps Ra 80-89
A light source with Ra 100 reproduces all colours exactly. Fluorescent lamps Ra 70-85
The lower the Ra value, the less precisely the colours are
reproduced.

RA 70-80 medium colour rendition RA 80-90 good colour rendition RA 90-100 very good colour rendition
