fluorescent lamps in terms of their technical characteristics.
In measurements, therefore, particular attention should be paid to the following (see
also DIN 5032):
1. Defined ageing of the lamp (100 hours)
2. Adequate burn-in time (stabilisation) before measurements are taken (15 hours)
3. Constant T
4. No destabilisation due to mechanical vibrations, even when switched off
5. High crest factor for lamp voltage (good rms instruments).
6. Short mains supply and measurement instrument wiring to the lamp
If these conditions are met, OSRAM DULUX
electrical and photometric values. Reference lamps measured under the following con-
ditions can be obtained from OSRAM (see 7.6).
Before photometric data is gathered, new lamps should be aged for 100 hours.
All compact fluorescent lamps must contain a small quantity of mercury in the
discharge tube in order to generate light. Some of this mercury, which is in liquid form,
vaporises when the lamp is switched on, while the rest condenses at the coolest spot
(cold spot). Because the discharge tubes of compact fluorescent lamps have such a
narrow cross-section, this transport process takes considerably longer than it does in
standard fluorescent lamps. For this reason, once new OSRAM DULUX
been aged by 100 hours, they must be „stabilised“ for a further 15 hours before pho-
tometric measurements are performed, otherwise it will not be possible to obtain
reproducible measured values. Between stabilisation and measurement, OSRAM

lamps (amalgam lamps) may be switched off for no more than 10 seconds.
Note: Stabilisation is not required for lamps without amalgam in the base-up position
if their position does not change after they have been aged for 100 hours or after the
last stabilisation process and if they are conveyed carefully when moved from the
burn-in position to the measurement position, avoiding any mechanical vibration,

ning position.
In the measurement position, the lamps should be burnt in for a further 30 minutes
before measurements are taken.
Exception: OSRAM DULUX
Because of the widely different spectrums of OSRAM DULUX
should be taken to ensure good spectral matching of the light receiver to the V ( ) curve
according to DIN 5031.
The requirements that the photometer must meet are the same as those for linear
