The QUICKTRONIC PROFESSIONAL QTP-OPTIMAL 2×54…58 is a multiwatt electronic ballast: it drives two fluorescent tubes, either T5 54 W (G5 base) or T8 58 W (G13 base). It recognises the connected lamp and adapts its operation — one unit in stock covering two tube families.
At high frequency the lamp no longer flickers and the stroboscopic effect disappears: visual comfort is far better than with a magnetic ballast, and consumption drops noticeably. Electrode preheating (≈ 1.5 s) spares the lamp at every start — which is what lets it take thousands of switching cycles without wearing the cathodes out early.
The starter is no longer needed: with electronic control gear it comes out of the circuit (or is replaced by a link if the luminaire requires one). At end of life, the cut-off function switches the lamp off instead of leaving it blinking indefinitely. Supply 220-240 V, 50/60 Hz.
Equivalents from other brands — with matching characteristics (same power, same range, same mounting), the job is done by PHILIPS HF-P 2 54 TL5 / 2 58 TL-D and Tridonic PC 2/54 T5 PRO. ⚠️ Always check overall size, terminals and starting method before replacing control gear in an existing luminaire: these differ between brands.

T5 54 W or T8 58 W — is there anything to set?
No. The QTP-OPTIMAL is multiwatt: it adapts automatically to the connected tube, T5 54 W as well as T8 58 W. Both tubes in a given fitting must, however, be the same type and wattage.
Do I need to keep the starter?
No. Electronic control gear handles preheating and ignition itself: the starter comes out of the circuit. When refurbishing a magnetically ballasted fitting, also remove the old ballast and the power-factor capacitor.
Is it dimmable?
No, this is a non-dimmable version (on/off operation). Dimming requires a DIM ballast (1-10 V or DALI), which is a different unit.
