Spotlight for low-
voltage halogen lamps
with integral, conven-
tional transformer.
Uplighter for compact
fluorescent lamps
or halogen lamps.
Spotlight for low-
voltage halogen lamps.
The extremely small
dimensions of the
lamp and the use of an
external transformer
allow the design of
compact spotlights.
Larger reflectors make
for enhanced optical
control and increased
luminous intensity.
Low-voltage track:
low-voltage spotlights
without transformers
can be operated on the
track. Power supply is
effected via an external
transformer.

3.3 Practical planning
3.3.7 Simulation and presentation
161
A graphical representa-
tion of the lighting
concept for the audito-
rium of a theatre. The
light beams are repre-
sented by hand-drawn
white lines against a
grey background. The
presentation is confi-
ned to the representa-
tion of luminaire posi-
tions, beam directions
and beam spreads.
It conveys a qualitative
overall impression of
the distribution of
light in the space and
deliberately provides
no quantitative data.
