Review by M. Wheeler for 400 Watt Electronic Switchable Ballast Hydroponic Grow Lamp System with Metal Halide and High Pressure Sodium HPS Light Bulbs, Cord + Hanger, GYO2002

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.
Update: I did buy the second unit and right now I have both using HPS bulbs finishing out my medicinal grow in soil. I sampled the product and give the results two thumbs up! Tiny clones to finished medicine in 90 days. With 2 400 watt bulbs and the two ballasts they do produce heat (all HPS and MH do). If you want to use these in a grow tent, you need to match the size (or number of lights) to the tent size and tent manufacturer’s recommendations for the type of lights and the power/heat. Don’t blame the light. Since a tent is confinement of space you will need positive ventilation. There is a very good reason why tents come with multiple vents for fans.

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.

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

Considering the price of the product, it’s decent.
The good: This is the cheapest full system setup you can get for $150.
The bad: The hangers work on a spring loaded tension type system, the problem I had was that one of the hangers pulled the hood up farther than the other one. So the level of the hood was off by like 45 degrees. I tried to adjust the tension but they were already at the lightest setting. So I had to lay a crescent wrench on one side to distribute the weight of the hood evenly. Also, the mh and hps bulbs are on the low quality side and produce quite a bit of heat and use a little bit more electricity than quality, more expensive bulbs. I have a small 2X4 grow tent and the temps reached up to 92 deg. I even had one fan blowing directly on it, and another oscillating with the tent completely open and temps were still unmanageable. So then I put two 265cfm squirrel cage fans in the tent, one for intake and one for exhaust, and still temps reached 88 deg.
The design flaw in this system: The hood. If you don’t have an open space with adequate ventilation, then you might have to invest in a ported hood like I did. I had to get a 6″ ported sunsystems hood and hook up a fan to it, now temps never get above 78 deg… perfect.
To recap- I’d recommend this product to anyone on a low budget. But beware, you’d better have an open, well ventilated space, or invest in some fans and a new hood if you want to manage temps. I WOULDN’T recommend this to anyone who plans to use this in a grow tent, unless you have some kickazz ventilation or unless you want to blast the AC. But it’d be more practical to buy a better system with a ported hood.
Well that’s my 2 cents.
