The new Yield Lab Slim Line 1000W Digital Dimming Ballast offers all the great features you\'ve come to love out of our ballasts with a slimmer design. With deeper heat syncs and a larger surface area, this ballast is lighter and stays cooler than other ballasts around. Made to work with both High Pressure Sodium(HPS) or Metal Halide(MH) bulbs and lamps, these ballasts are still comparable to- if not better than- the Quantum Horticulture Ballasts series. With the dimmable feature, you are able to reduce excessive heat during hot days by turning the dimming knob as low as 50% of the light\'s heat emission as well as reducing lumen intensity during early plant growth and providing high output intensity during later stages. Reducing the light intensity also provides a more comfortable area to work under when pruning or maintaining your grow area. Having a dimmable ballast will greatly reduce heat output, prevents burning of plants, improves quality and control, and helps you save time, energy, and money
