Those are some kind of industrial lights...I would be afraid to use them, myself.

If you do use them...I would find an electrican friend to check them out.

My advice: sell them and get a separate ballast, bulb and reflector deal online. Google: grow light systems....:thumbsup:

All plants are about 3 feet tall, maybe not even. ALL are females. They are all topped once. some stacked better than others and some stretched because of the light :(. Now My question is Rating: 5
