The new digital light ballasts offer several advantages over other types of ballasts. One is that they weigh less than the other types. This is an important consideration when you are hanging several lights above your plants. Another is that they run silently and have a greater efficiency. Both of these points will save you aggravation and money. The digital versions of ballasts have quicker start-up times and they come in compact designs. This mean you can fit more grow lights into a smaller space.

The digital ballasts also allow the lamps to put out more light than other ballasts. This will save you a lot of money over time since it allows the grow bulb to put out twenty to thirty percent more light, yet runs on the same amount of electricity.
