Typical run-up behavior of OSRAM DULUX® L SP lamps in a side surface mounted luminaire until 90 % of the
luminous flux is reached.
Typical run-up behavior of OSRAM DULUX® T/E HE (high efficiency lamps) in ECG operation (long off time),
25 ºC ambient temperature, mains voltage 230 V/ 50 Hz, free-operating horizontal
Run-up behaviour of DULUX® CONSTANT lamps.
The run-up behaviour of DULUX ® CONSTANT lamps is different, slower compared to the standard
Cold Spot DULUX ® lamps. That’s because the amalgam in the discharge vessel absorbs almost all
of the mercury from the gas in the tube, during the off time period, and needs to heat up properly
after ignition, to release again the mercury to the discharge. Therefore DULUX
® CONSTANT lamps
run-up slower or start even as mercury free, with pink light output for a short time, until the amalgam
