PERFECT LIGHTING, BOTH FOR YOU AND THE ENVIRONMENT

Are energy-saving bulbs an effective
substitute for filament bulbs?
The good old filament bulb has in
recent years been criticised as an
energy waster. Due to its excellent
colour rendering index of Ra* =
100, it is, however, the first choice
when it comes to enhancing the
ambience and the sense of wellbeing.
On account of the perceivably
poorer colour rendering index of
Ra* = 80, the much-lauded
energy-saving bulbs or compact
fluorescent bulbs are, at best, an
effective substitute in areas in
which a lot of time is spent or
where saving energy is more important
than the colour rendering - e.g. in
hallways, staircases or storerooms.
* As is the case for daylight, artificial
light should also enable as an
accurate as possible perception of
colours. The benchmark for this is
the colour rendering properties of a
light source which are described
with the colour rendering index

Atmospheric light and energy
saving - is that possible?
With a colour rendering index of
Ra* = 100, halogen bulbs emit
colours of the same quality as
filament bulbs. 12 V halogen bulbs
with an infrared coating on the
bulbs (IRC technology) coupled
with an electronic transformer also
result in savings in energy of more
than 40% in comparison with
traditional filament bulbs. With a
service life of 4,000 hours, these
bulbs also last four times longer.
Ideal for high class conference
tables and elegant workstations.
Thus, you can save energy
without having to compromise
on ambience.
"Ra". This index is between 0 and
100. The higher the index, the
better the colour rendering; 100 is
the optimum index.

When should I use energy-saving
bulbs?
Energy-saving bulbs consume
approximately 20% of the energy
of a standard filament bulb and last
ten times longer. Energy-saving
bulbs have a colour rending index
of Ra*=80.
These bulbs are suitable for areas
where lights are on for long periods
of time but where not much time
is actually spent, such as hallways
and staircases.

LED
Do LEDs save energy without
compromising on ambience?
LEDs are undergoing a highly
dynamic development. Today, they
already achieve up to 100 lm / W
and are therefore one of the most
economic light sources.
Due to the efficient light projection
and very few scattering losses,
remarkable brightness with little
energy has now been achieved.
LEDs are extremely small and can
be integrated into many locations
where traditional light sources
prove too large, e.g. onto beds as a
reading light or in display cabinets
to show off valuable objects.
Coloured LEDs are ideal for
fascinating effects, such as in
illuminated ceilings and walls as
well as on furniture and in coves.
White LEDs in a warm tone design
are currently available with a
colour rendering index of Ra*=80.
They are therefore only recommended
for areas in which very good colour
rendering is required, such as
for illuminating colour pictures.
LED light is particularly well
suited for reading books. Use LEDs
specifically for providing
sophisticated light in selected
areas, and thus save energy.
