Fluorescent lamps
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-D lamps are low-pressure
mercury discharge lamps with a
clear tubular 26 mm envelope.
The tube wall is internally
covered with a mixture of
fluorescent powders.
TL-D Standard colours have a
moderate colour rendering index
(C.R.I. 50 - 75). Especially the red
part of the spectral power
distribution is moderately
covered by standard colours.
TL-D Standard colours are
mostly used in applications
where colour rendering is not an
important parameter.
The efficacy of TL-D Standard
colours is lower than TL-D /80
colours.
The colour designation of TL-D
lamps creates a certain
atmosphere. It varies from warmwhite to cool daylight.The colour
designation is determined by the
colour temperature of the lamp.
