The Yield Lab 400w HPS Cool Tube 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 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. 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 Grow Light Kit also includes a Yield Lab HPS (High Pressure Sodium) bulbs, a light hanger set, the Yield Lab Air Cool Tube and a free timer.

Light kit

Excellent product works as it should very happy, Will order from growace again


Well-designed, and comes with two bulbs. One for veg stage. one for flowering. Easy to raise and lower.Ideal for 4X4 box. Dimmable. Great value


I have been using one for almost two years now, and the results I get are amazing!!! Let's just say I get my watts in weight !!!! It's a very lightweight light , and also easy to cool . With dimming options and bulbs hanger and timer included you can't lose. they have the absolute lowest prices for the quality of their fixtures I love them so much I told 4000+ growers to check them out and I recently got a second one !!!! I will ALWAYS use GROWACE !!!! for me they are the only source for lighting . Don't believe me walk into a hydroponic store and price similar fixtures with similar warranties and GROWACE also always honor the warranties on these things I'm telling you all you just can't beat these lights anywhere !!!! PERIOD !
