Phantom 2 digital ballast 1000 watt New!!

Digital ballasts generally have the option to adjust the wattage they are running at. It means you can use either a HPS or MH lamp with the same ballast, and even change between 400w lamp and 600w lamp for example. With a magnetic ballast, you would have to buy dedicated ballasts for each wattage of lamp. Many digital ballasts will have a soft start feature, used to slowly release power to the lamp to extend its bulb life.
