    Even better than I expected!
    Review by Paulon 2017-03-08
    Haven't started growing yet but mine arrived today and I'm impressed. Some of the labels English isn't the greatest but my model now has a switch for each light intensity. Each intensity runs one fan rather than both all the time so can be quieter as well as more efficient. I ran the light in a 2x2x4 tent for several hours with a 4in fan at it's lowest setting and there was no noticeable heat even directly in top of the unit, it was basically cool to the touch. Now I may have to find a way to to heat my tent because the lights are so cool!

    Can't wait to start growing!

    Amazingly Efficient Results!!!
    Review by TripleEon 2015-04-10
    This product is excellent...
    It is quiet and doesn't put out much heat.
    The soil and soilless plants have reacted extremely well to this light.
    The density of the canopies is unreal.
    The inter-nodal length is the best I've seen at 1" increasing yields heavily.
    The foliage is beautiful.
    Only down side is you need special glasses or the light messes with your eyes.
