HID bulbs must connect to a ballast for them to work. Ballasts provide the necessary electrical current to run the bulb and also to initially ignite the lamp when it is switched on.

We stock two different types of ballast: Magnetic and Digital.

Magnetic ballasts use a traditional core and coil to power the light bulb

Digital ballasts feature a computer chip inside them to control and ignite the bulb

There are lots of cheap ballasts hitting the market these days, we have kept our range fairly small to be sure to offer only trusted brands, which work well and will not prematurely fail. All of these products carry a 1-5 year guarantee too!
