The following glossary of terms will help you when selecting lamps in this section.
Within each product line, lamps are divided into families – within these families,
lamps are listed by wattage. The Product Description can be used as a quick
reference to each product’s attributes. Where Life or Average Life are stated we
refer to the industry standard definition of how many hours of operation 50% of a
given installation will exceed.
Additional parameters:
CCT [K]:
Colour Temperature – Kelvins
A measure of the visual “warmth” or “coolness” of the light
from the lamp. The higher the value the whiter or “cooler”
the light appears.
CRI [Ra]:
Colour Rendering Index
An indication of the ability of the lamp to render object
colours in a normal, natural way. The higher the number
(0-100), the better the colour appearence.
