ELECTROMAGNETIC BALLASTS - Всичко за вашите растения!
Low price, decent service life, good performance are the main advantages of Magnetic ballasts. A thermal fuse and protection against overheating are standard. The disadvantage is more demanding wiring, higher weight and imperfect lighting efficiency. You can't even regulate the output of the lamps with these conventional ballasts. We recommend PURE LIGHT 400W and PURE LIGHT V2 600W as the magnetic ballasts with best price-quality ratio.
