The reason I talked about the lumen max 3 and I think pitbullpooch recommended the lumenarcs (don't know if it comes with a glass shield, but if not, you need one with HQI bulbs) is increase in light penetration and spread. I think both of these are made by Sun light supply.The setup you are looking at is a standard reflector that is not as good as the ones we named. The lumen is very similar to the diamond reflectors from a few years ago which were twice as good as the standard reflector, but the cost was very high. These reflectors are a lot cheaper and seem to be just as good. Not saying you need them but since you are setting up a new lighting system why not go with the top of the line reflectors and be done with it.
The reason I recommend the pendent over just a reflector is because it is easier to sell a pendent then just a reflector. You can mount the pendent inside a canopy if you want. It is very easy you just need some L brackets.
Keep in mind this is only one of many lighting options you have with that tank, that is why I am just outlining your choice. If you want to talk T5's I can explain the setup you would need and how to place it, will T5's work with SPS YES but that was not your question and it will cost more up front for a T5 setup for your size tank then MH double ended bulb setup. To get it right I would say 16 - 3' bulbs with ice cap ballasts so as to over drive the bulbs and fans to keep the bulbs cool.
Also remember with any lighting option the reflector will determine the light penetration, spread and direction.
The last item you will need to consider with MH lighting is heat. These bulbs/lighting systems create a lot of heat, just something else to think about.
