It is basically possible to operate OSRAM DULUX
pin bases in conjunction with motion detectors and light sensors. Bear in mind that in
these arrangements the lamps operate only for short periods before switching off
again, so the run-up time for light output (the time the lamp takes to reach 100 %
luminous flux) and the reduction in lamp life due to the high number of switching ope-
rations are factors that must be taken into account. (see 2.4.4)
CCG-operated lamps should not be used in applications with extremely frequent
on/off switching. Instead, only compact fluorescent lamps for ECG operation should
be used. The ECG should be selected to ensure optimum lamp starting every time.
Stand-by operating modes are ideal for such applications. In stand-by mode the light
is dimmed when it is not needed. This avoids unnecessary switching operations and
saves energy. Because the light is never fully switched off there is always a certain
amount of light available for people to find their way around. Full light is available
instantly, with no pre-heating delay. Typical applications for stand-by mode include all
those with frequent on/off switching, such as stairwells, corridors and underground
garages. Particularly if the light is controlled with motion detectors or time switches.
Information on the maximum permitted number of luminaires per automatic circuit-
breakers can be found in the OSRAM Lighting Programme.
