400w HPS+MH Wing Reflector Grow Light KitAdd to Favourites
With the dimmable feature on this 400 watt HPS grow light, 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. You are also able to reduce lumen intensity during early plant growth and provide high output intensity during later stages. 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 400 watt HPS grow light kit also includes a Yield Lab HPS (High Pressure Sodium) bulb, a Yield Lab MH (Metal Halide) Bulb, a light hanger set, the Yield Lab Adjustable Wing Reflector and a free timer.
