Do you know the color tempature of those small lights? Keep in mind
you'll want something above 6500K for good growth and if you want them
to look nice you'll want something in the 14000 range.

Does a good job of showing the differences in the Kevlin rating of
different bulbs.

Have you been to www.nano-reef.com?
If you want to see pictures of a 70w MH working LOOK THERE.

Thank, I will look there, but 70W seems to be too much...
I had a quad power compact tube 96W and it was TOO much light.

Also... where have you seen a 20-30w MH?

Not in the fish tank market, but they are popular as small spot lights:
