TL Standard colours
Fluorescent lighting is efficient and TL Standard colours are mostly
economical.The efficacy
used in applications where colour
rendering is not an important
factor.
The colour designation ofTL
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.
(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.
