Ballasts can be distinguished in two kinds. The first is the traditional magnetic ballast. These have been on the market for decades, they work fine and are a lot cheaper. However, the electronic or digital ballasts are much more efficient when it comes to turning electricity into light. Instead of turning a large part of the consumed electricity into heat and noise they only produce what it is all about….LUMENS. Advanced digital units also have features such as dimming or the ability to overrun your lamp for higher light output.
All ballasts in the web shop are CE approved and are selected for their high efficiency.
