Hell of a price, I'd take the deal regardless of hood (reflector) and hope I get a larger growspace later-on. :thumbsup:

Bare Bulb - Uneven lighting, wasted lumens. (nothing reflected back to the plants)
Bat wing - crappiest of the bunch, barely better than bare-bulb. Uneven light distribution.
Parabolic reflector - barely better than a bat wing, but good enough light distribution for commercial grows.
Enclosed hood - better for enclosed area's or rooms with limited ventilation, but restricts light 'footprint'.
Cool Tube - Lowers heat from bulb, but is a pain to maneuver and takes-up a lot of space.

I prefer an enclosed hood, but it would depend on your intended use, quantity of lights you'll be using, ammount of growspace, ambient temperatures, venting and air circulation...
