Ballasts power HID lamps by regulating voltage. They are necessary for HID lamps to function well.
In comparison to a magnetic ballast, a digital ballast is very efficient and cost-effective in the long run. Digital ballasts are reliable and offer better performance. Dimmable ballasts can be customized, meaning you can use the same one for different types of HID lamps and lamp wattage. They generate a small amount of heat and usually have built-in protection against short-circuiting. A soft start feature will prolong the life of your HID lamp. By using a digital ballast, you will avoid uneven or flickering lights.
We sell ballasts made by various brands, but the clear favourite is the tried and tested German quality by Lumatek.
