If one compares the data for the LED
module with a correspondingly sized T2
lamp (e.g. FM 13 W/730 lm, 71.5 lm/W), at
first glance, it appears that the T2 lamp has
better
particularly with regard to luminous flux and
efficiency.
In practice, however, it can be seen that the
LED variant, constructed as a narrow light,
possesses considerably higher system effi-
ciency than the light with the CCFL lamp
(Figure 9).
With the CCFL lamp, only a small portion of
the total available light can be used, due to
self-shadowing by the CCFL and design-
related issues. For a CCFL with an optical
efficiency value of 72 m/W, this means that a
real efficiency value of only 43 lm/W can be
used in the system.
With the LED light nearly 100% of the
luminous flux can be used, due to the
unidirectional radiation of light, in which the
system efficiency is equal to the LED

efficiency. At higher color temperatures, the
superiority of the LED with respect to the
CCFL is even more apparent (e.g. APT Plus
LUW G5GP
6500 K).
In addition, the LED light has further decisive
advantages in comparison to the CCFL
variant for its use in illumination. As a rule,
warm white LEDs have a higher color
reproduction index (Ra = 80) than CCFL
lamps (Ra = 70-78), whereby the different
colors are better reproduced or more easily
distinguished.
In addition to this visual advantage, LEDs
also have other advantages in comparison
to CCFL lamps, due to their packaging
