My main tank is a 40b, co2 injected and is located in my dimly lit living room. I like having the lights sitting on the tank rim to help keep light out of everyones eyes when we are watching tv etc. Would it be a good idea to run 6x21w no tubes? I already own 2 2x21w fixtures but im debating if this is enough light for me. It comes down to 6x21w t5no on the rim or 3 t5ho tubes hung above the tank.

Ps. My substrate is about 14to15in from the rim.

Personally I'd do what I had to, to get them to sit on top. I think 2 36" t5ho would be good.

I run one 36" ho on top of my 30g and it is pretty decent.

you could but its more what plants you have on the bottom. high light carpet like hc? not a chance. low light crypts? sure. 40b are really wide @18" but i dont think you would need 6 of them 4 at the most should be good.
