The Grow Ace Optimal 400w HPS Cool Hood Reflector Digital Dimming Ballast Grow Light Kit comes with everything you need for an efficient lighting source for your plant or garden. Comparable to Quantum Horticulture Ballasts, the 400W HPS grow light kit includes the new Yield Lab digital ballast that offers great benefits and more control over your grow light system. 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 with this 400W HPS grow light kit. You are also able to reduce lumen intensity during early plant growth and provide high output intensity during later stages with this 400W HPS grow light kit. Reducing the light intensity also provides a more comfortable area when working in your garden. 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. This 400W HPS Grow Light Kit also includes a Yield Lab HPS (High Pressure Sodium) bulb, a light hanger set, the Yield Lab Air Cool Hood and a free timer.
