preheat start even after a turn-off followed by an immediate lamp
restart. OSRAM QUICKTRONIC ignite the lamp always with optimum
preheating of the electrodes. A particular off-time with regards to
lamp life is not necessary.
2.6 Behaviour in Response
to Lamp Defects
What do we mean by lamp defect or end-of-lamp life?
In most cases, it is not possible to see from outside which lampholders are
assigned to which ECG-terminals, so if you insert lamps and they fail to
start automatically you should take out the first lamp again and refit it. Both
lamps should then light.
Lamp replacement of 2- and multilamp luminaires proceed as follows:
Insert the lamps. If at 2- or multilamp luminaires lamp ignition doesn’t work
automatically, take out the lamp replaced first and refit it. Reignition of both
lamps works automatically.
