Lighting over 65g

[Kronk]

Would a 150w HQI and a 250w HQI look "off balance" if put them over a 3ft long 65g tank?

I currently have a 150w HQI retrofit with electronic ballast over a 20g and I am debating getting another of the same or a 250w HQI to put over the 65g. I will mostly be keeping softies and LPS. Also the tank will be in a livingroom which i dont want totally dominated by the aquarium lighting.

Thanks,
Ken
