Colour rendering - a spectrum of brilliant colours

Colour rendering determines whether the light makes
colours appear bright and vibrant or dull and soft. It is
a function of the lamps themselves (e.g. incandescent
lamp, halogen lamp, fluorescent lamp). Lamps are
divided into colour rendering categories such as 1A,
1B, 2A, 2B and so on. Category 1A provides the best
possible rendition of colours.
A colour rendering index of 1A is always recommended
for areas where people are working.
