Operation with

motion detectors

and light sensors

It is basically possible to operate OSRAM DULUX® compact fluorescent lamps with

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.
