Parameters for the effects of light Colour temperature (measured in Kelvin) The colour temperature is the measure for the colour impression of a light source, measured in Kelvin (K). The standard for sunny daylight is 5,500 K, in fog approximately 8,000 K and just before sunrise it is up to 12,000 K. Artificial light imitates various light situations: The light emitted by a fluorescent tube achieves a colour temperature of up to 5,000 K, halogen light to 3,000 K and a candle to 1,500 K. Illuminance (measured in Lux) Illuminance (commonly called light level) is a term that quantifies light incident on a surface. It is influenced and reduced by the distance of the source. Light Distribution: This simplified diagram is intended to act as an aid for the planner and shows the light intensities at a distance of 50 cm, which is applicable to a light in furniture. It was measured in a black box without ambient light with a standard lux metre. Specified is the maximum value in the centre. The angle can be calculated based on the loss in light up to half-peak intensity. 12V/1.25W 12V/1.5W 22° max. 1700 lx 62° max. 114 lx 50 cm 12V/50W Order by phone, fax or internet (P) 1.800.423.3531 (F) 1.888.646-4349 22° 35° max. 1700 1260 lx Spotlights for small areas The most popular angle for spotlights is 35° 230V/21W 180° 50 cm 50 cm max. 250 lx 50 cm Floodlights for soft lighting Fluorescent tubes for surface lighting situations Lighting 92
