Lighting Capacitors

Lighting capacitors are a key component in the control gear of discharge lamps, such as high-pressure sodium or metal halide lamps, because they correct the installation's power factor. At GreenIce we stock ready-to-install capacitors for street, industrial and outdoor lighting gear, so you can keep your fixtures in perfect condition.

Which capacitors you'll find

The category currently includes a 35 µF capacitor, rated at 250 Vac, with 10% tolerance, suitable for 50/60 Hz networks and fitted with 200 mm leads for quick connection inside the fixture's gear box.

What a capacitor does in lighting

Discharge lamps need an electromagnetic ballast to operate, and that ballast consumes reactive power. The capacitor, connected in parallel with the supply, compensates for this reactive power and brings the power factor closer to 1. The result is lower current in the line, fewer cable losses and no penalties for reactive power consumption in large installations.

It's commonly replaced during maintenance of street lights, floodlights and discharge high bay lights, since it loses capacitance over the years. If you're thinking of upgrading, you can also switch to LED bulbs for street lights, which need no ballast or capacitor.

How to choose a lighting capacitor

Capacitance (µF)

It depends on the wattage and type of lamp and ballast. Always check the label on the gear or on the capacitor you're replacing and keep the same value.

Rated voltage

It must be equal to or higher than the operating voltage. A 250 Vac model is suitable for 230 V networks.

Connection and space

Check that the dimensions and lead length fit inside your fixture's gear box.
