I use a less fancy version set up in a tote. The stuff can all be had at home depot in the Electrical or lighting areas. Rather than mount to a hood, I just made holes in the lid of the tote. The y adapter for the bulbs is two parts. They sell a base for a single bulb that has a regular outlet on the other side, you then screw the Y adapter into the bulb outlet, one part on each side of the lid so it stays in place. I should probably rig up a pc fan for venting, but cracking the lid works fine. I keep clones and seedlings in there till I am ready to use them.
So long story short, that's a great little setup for veg.
