Maximum economy
can be achieved by using
the FH
arrangements based on
T8 lamps (26 mm).
The following factors add up
to a reduction in electricity
costs of 20%:
– the luminous efficacy
– the 40% reduction in tube
– the shift in optimum lumi-
of the FH
5% higher than that of
T8 lamps
diameter results in a 5%
increase in luminaire effi-
ciency thanks to a much
reduced shadowing effect
from the lamp itself
nous flux from 25° C to
39° C results in consider-
ably more light from the
luminaire.

The diagram compares the
shadowing effects caused
by T8 and T5 lamps in a
T8 reflector. The new
FH
of only 16 mm represents a
much smaller obstruction
to the light rays than the
26 mm lamp, so less light
remains trapped in the
luminaire.
