no drama, is there a downside to these kind of lights? do the ballasts burn out quicker because they are at the light? they are a good deal cheaper than grow lights.
when splicing the wires (if that is what it is even called) do you use those twisty things or just twist the wires together and use electrical tape?
Electrical tape will "work", but caping them gives a better connection. Wiring something that powerful with electrical tape is a bad idea anyways.
I know some people don't take the ground (green) wire too seriously, but its actually
VERY IMPORTANT, especially considering this light will many times be in directly contact with you. If for some reason the white (neutral) wire fails, the electric current will find the nearest source to travel to the ground. If that happens to be your hand as you move the light to one side...you will get more than just a light shock. Even worse, since water is in the picture, the result can be very serious. Ground the wire!
Also, make sure the outlet you're plugging into supports your light, if it doesn't...again...seriously bad things can happen. A lot of house fires start this way with poor wiring.
Its cool that you got a deal and all, or however you came about that light, but make sure you know exactly what you're doing. Better safe than sorry.
