CCT
|
The correlated colour temperature (CCT) is a specification of the colour appearance of the light emitted by a lamp, relating its colour to the colour of light from a reference source when heated to a particular temperature, measured in degrees Kelvin (K). |

Chemical Resistance of Luminaire Materials
|
Industrial luminaires are manufactured in a variety of materials, each specifically selected as being the most resistant to chemical corrosion & other related elements. The resistance tables give a general overview regarding the resistance to chemical attack on luminaire materials and generally applicable for ambient temperatures up to 60˚C. |

Color Rendering
|
The rendition of colour by a lamp is specified by the CIE colour rendering index (CRI or Ra) and is a measure of the light source to faithfully render the appearance of a gamut of colours spanning the colour space. |

Hazardous Locations
|
A hazardous area can be defined as any location where there is risk of an explosion. But every hazardous area is different and each has specific requirements depending on the nature of the atmosphere and the elements that are present. |
