Are energy-saving lamps an effective
substitute for filament lamps?
The good old filament lamp 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 lamps or compact
fluorescent lamps 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
"Ra". This index is between 0 and 100.

Atmospheric light and energy
saving - is that possible?
With a colour rendering index of
Ra* = 100, halogen lamps emit
colours of the same quality as
filament lamps. 12 V halogen
lamps with an infrared coating on
the lamps (IRC technology) coupled
with an electronic transformer
also result in savings in energy of
more than 40% in comparison with
traditional filament lamps. With a
service life of up to 5,000 hours,
these lamps also last five times
longer. Ideal for high class
conference tables and elegant
workstations. Thus, you can save
energy without having to
compromise on ambience.
The higher the index, the better the colour
rendering; 100 is the optimum index.

When should I use energy-saving
lamps?
Energy-saving lamps consume
approximately 20% of the energy
of a standard filament lamp and
last ten times longer. Energy-saving
lamps have a colour rending index
of Ra*=80.
These lamps 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 not 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.
The standard filament lamp (100%) is compared with
lamps with a comparable luminous flux (± 12%).
