Replace both lamps, take out the lamp replaced first and refit it. Provided 
lamp and ECG are o.k. both lamps should then light.

…HO and FC start the lamps at any time with optimum 
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.
