Also, the new reflector doesn't have one of those "V" shaped light deflectors that go above the bulb. How much do those actually effect my lighting?

your not going to be able to cast optimal lighting with one bulb on a 36" tank. If you go by the rule of thumb 2X2 foot for each SE bulb, you will see that like my Garage tank, no matter how you place the bulb on the tank you are going to have areas that have much lower light intensity.
the way I would do it if I were you is on an empty tank or maybe the kitchen floor flash your light up with white paper under it and see how the lighting patteren is.. then you can shift it around to the point you are happy with it.
