400 watt HPS HID "Shop Lights"

Is it stupid to try and use a 400 watt hps hanging style shop light. Obviously new bulbs would likely be in order?

Jesus thats alot of lights^ I don't see any ballasts though.

I saw these used in a large warehouse garden(5000'sq), They seemed to be doing the trick.

Thanks folks.

yeah i dont see why not. as long as it isnt going to throw too much heat into your room

The ballast is internal, it's that little white box thingy on top.

My setup actually utilizes a similar light, except mine is designed for parking lots ect.
They work just fine but make sure that the ballast is set up to run on house current.

they're configurable for 120 but currently at 240, no big deal there tho; switch a couple wires and game on! I'll likely mod them by cutting a vent hole and rigging a dryer air duct to it and draw the hot air out of the reflector/ballast and out of the room via a 6" fan or something close to that.

Thanks for the input!
