2 Introduction The function of starters is to preheat the electrodes of fluorescent lamps and generate an ignition pulse. While the lamps are in operation the starters should consume little or no power and be ready to operate again as soon as the fluorescent lamps have been switched off. A high-quality starter will last at least 40,000 on/off switching operations (such as OSRAM ST 111 LONGLIFE). ® The DEOS SAFETY Starter also reliably switches off the fluorescent lamps at the end of their lives.
4 Starters ST 111 / ST 151 (LONGLIFE starters) 4.1 Design The glow starter contains the actual starter element, the glow igniter, and the radio interference suppression capacitor. It is connected parallel to the lamp in series with the lamp electrodes.
The bimetallic contacts cool down and open again. The energy stored in the choke now discharges. (induction law) A voltage pulse (Umax) is generated which ignites the lamp. Once the lamp has ignited only the lamp voltage (UL) is applied at the glow starter. This voltage is less than the partial discharge inception voltage. It is so low that there can be no further glow discharge between the bimetallic contacts.

In addition, fluorescent lamps that are faulty or at the end of their lives are safely and reliably shut down. 5.
6 Overview of starters An overview of the types currently available is given below.
7 RoHS The starters meet RoHS requirements (Reduction of Hazardous Substances). The glass used (bulb, exhaust stem, flare) is lead-free. 8 Disposal The starters may be thrown away with household waste. 9 Troubleshooting 9.1 Observation: the lamp fails to ignite, the starter switches without interruption Cause: The lamp voltage is too high (lamp at the end of its life) Remedy: Replace the (compact) fluorescent lamp and starter (ST 111 LONGLIFE/ ST 151 LONGLIFE) 9.
9.6 Observation: the lamp does not start, the starter casing has a brown discoloring Cause: The starter is at the end of its life, the bimetallic strips can no longer close Remedy: Replace the lamp and starter 9.6 Observation: radio interference Cause: The compensating capacitor is missing from the starter or is faulty Remedy: Replace the starter 9.7 Observation: the lamp ignites and goes out at short intervals Cause: The lamp is at the end of its life Remedy: Replace the lamp and starter 9.
