Vossloh 1x18w T8 Switch Start Choke

The Vossloh Schwabe 1×18 W T8 Switch‑Start Choke is a magnetic control gear unit designed specifically for one 18 W T8 fluorescent lamp (or similar switch‑start configuration) operating off a 230 V 50 Hz mains supply. The product supports the traditional filament‑pre‑heat ignition method typical of older T8 switch‑start fittings. It is best suited for retrofit or replacement scenarios in existing luminaires where high‑frequency electronic gear has not yet been installed, preserving original wiring and starter components.

Installation is straightforward: the choke replaces the ballast in the gear tray of the fitting and works in conjunction with the conventional lamp and starter setup. As with all switch‑start gear, a starter must be fitted alongside and appropriate for the lamp type. Due to its magnetic design the unit introduces a modest loss compared to modern electronic gear and is suitable only where compatibility with the existing T8 lamp and starter circuit is required. Always check the ambient temperature rating, wiring integrity and fixture access to ensure safe operation.
