T5 light combination

[cvrle1]

Hey,

I was doing a lot of reading, but can't decide on what combination of T5 lights to use. It seems that each company has different naming convention for the same bulb so that confuses me even more. I have 4 34" HO bulb system over a 33 gallon tank. I would like to keep softies, LPS and SPS corals (not sure which ones yet) and maybe a clam down the road. I know that I would be able to do this with the setup I have, but as I mentioned not sure what the best combination of bulbs would be.

Also, should I buy bulbs locally or should I go with internet.

Thanks for the help.
