Colours you can feel. Conserving precious objects. LED spotlights offer a new kind of lighting quality UV IR green 400 500 600 700 800 TEMPURA produces white light by additive colour mixing of three narrow-band primary colours (RGB). In terms of colour rendition, this light is nothing like light from a broad-band conventional light source. red blue Colour rendition Level (CIE) 1A 1B 2A 2B 3 4 RA (DIN) > 90 80 ­ 89 70 ­ 79 60 ­ 69 40 ­ 59 20 ­ 39 Examples of lamps Innovative LED technology has opened up a broad range of intense colours and subtle white tones. The dashed line encloses the colour spectrum of the TEMPURA spotlight on the CIE 1931 colour space chromaticity diagram. Every colour and every non-primary colour bounded by this line can be set on the LED luminaire.

This makes people appear attractive and healthy." Standard EN 12464-1 characterises colour rendition in these terms. The following points must be noted when assessing the colour spectrum of LED lighting solutions: · The definition of the term "colour rendition" was specified on the basis of the state of knowledge at the time of standardisation and relates primarily to continuum sources (incandescent lamps). · Colour rendition as standardised at the time does not always correspond to the visual impression of colour. There is also no correlation with lighting using daylight. · Colour rendition relates only to white light and few reference colours. A theoretical match in all reference colours does not constitute evidence of a perfect light source because there may be considerable deviations in all other colour tones which are not evaluated in the standard.
