There are lots of lights that will get you high light in your tank. Personally, I have a BML 30" 10000K fixture. And it gets me into the low range of high light at the substrate and well into high light everywhere else. I can't think of a plant I shouldn't be able to grow in my tank with this light.
I used current usa t5 ho fixtures on my 29G with great success. Not sure if you can still find em though. 30" used to be tough to find decent stuff for but now with LED there's lots of options like the one mentioned above. Also the new current satellite stuff and finnex fixtures. Just remember if you want a med to high light carpet you'll have to get some something pretty strong in the par department due the 18" depth on a 29G.
