Remote ballast actually keeps a significant amount of heat away from the bulb/fixture. Both included bulbs are very decent quality/spectrum.

This product does work very well for growing medicinal herbs. My plants are growing very rapidly, as much as an inch a day on a 12 inch plant. The heat output is manageable: I have a 10″ box fan pointed at the ballast that also circulates air in the grow room so the light stays cool, too. The design is no frills utilitarian, with long long power cords. The manufacturer also sells replacement bulbs for under $30 each. I believe this unit is an excellent value, and I plan to buy another one so that I can have one in vegetative mode (MH bulb)and another in bloom mode (HPS bulb) to maintain constant production. I highly recommend this product.

Not the highest quality, but more than enough for the price. Working with MH and HPS, plus including each bulb makes this price a STEAL. The seller was in state so I recieved the unit in about 4 days.
