So over a 20g long, running one 24 T5HO bulb would be considered medium light?

I'd say that would be a pretty accurate statement. It wouldn't be higher end medium, but it would be medium. 2x24w would be enough to grow just about anything. I kept a 2x39w on my 40 breeder until recently when I went with 4x39w. I grew a lot of plants that 'require' high light with no problems. That would be pretty similar to a 20 long with 2x24w IMO

it depends greatly on how high it is positioned over the tank and the quality of the reflector.

This is a good chart to get an idea of what you'll be working with, it's not the be all/end all or anything, but it's not meant to be.

How do these fixtures compare to higher priced ones, or some of the catalina ones? I've been reading about posts for days that say to stay away from lower priced lighting, because in the long run they can be dangerous or just a plain waste of money. Im looking for similar lighting, but dont want to have to dose co2.
