TL Standard colours are mostly
used in applications where colour
rendering is not an important
factor.
The colour designation of TL
lamps creates a certain
atmosphere. It varies from warm
white to cool daylight.The colour
designation is determined by the
colour temperature of the lamp.
Fluorescent lighting is efficient and
economical.The efficacy
(lumen/watt) of all fluorescent
lamps is high compared to most
other light sources.
Different luminaires are available
for various purposes.
TL lamps are low-pressure
mercury discharge lamps with a
clear tubular 38 mm envelope.
The tube wall is internally
covered with a mixture of
fluorescent powders.
TL Standard colours have a
moderate colour rendering index
(CRI 50-70). Especially the red
part of the spectral power
distribution is moderately covered
by Standard colours.
