Beamworks from Aquatraders is used a lot over at plantedtank.net. I use their T5 for one of my planted tanks. Some insist they are too cheap but i have never had a problem. Check out plantedtank for more ideas.
I don't think a planted tank light will work for this, you'll need higher spectrum and more intensity. Try a par38 bulb + fixture, or look for a cheap TAO led panel (both will be more than enough for your tank )
I can pass on links for either or both of those options if you want!
