Currently, mainly fossil fuels are used to generate electrical energy. This
results in two fundamental problems:
1. fossil fuels are finite
2. they force climate change
The task of the luminaire manufacturer is therefore to develop the most
efficient luminaire systems possible while at the same time improving the
light quality for the user.
PERFORMANCE IN LIGHTING product development has set store by efficient
light sources and operating devices from the start. For example, only T5
illuminants and electronic ballasts were used for the development of office
luminaires.
Since 2001 PERFORMANCE IN LIGHTING has been supplying only products
with electronic operating devices, making an important contribution to
energy efficiency and to going easy on natural resources.
A further important criterion for energy efficiency is the materials used
for directing light. In this case PERFORMANCE IN LIGHTING sets store by
reflector materials metallised in a high vacuum with very thin coatings of
aluminium. This ultra-pure aluminium has a very high efficiency level which
produces a very efficient light direction. PERFORMANCE IN LIGHTING uses
this high technology for both downlights and linear fluorescent luminaires.
Since silver has a higher reflectivity over the whole spectral range than
aluminium, PERFORMANCE IN LIGHTING uses specular louvers with a silver
surface for the high-quality SL 787 series. This again achieves a considerable
increase in efficiency.

The corridor function, by providing sufficient light, always ensures safety
and a pleasant atmosphere. To this end the correspondingly equipped
operating devices are factory pre-programmed to provide the connected
luminaires with 100% dimming value when someone is present and a 10%
dimming value when no-one is present. The transition, which is pre-adjus-
table to dim within a certain time, can, like the corresponding dimming
stages, very easily be adapted to individual requirements.
By connecting commercially available relay motion sensors (or staircase
time switches), when a 230 V mains voltage signal is applied to control
inputs D1 and D2, the light value is increased e.g. to 100%, and after shutoff
of the motion sensor automatically set back to the programmed dimming
value.
Additionally, there is the possibility of regulating the dimming value
through a special daylight sensor when someone is present. The device
will then dim automatically to the desired dimming value depending on
daylight.
