I would imagine that hoods that produce 4+ watts per gallon on a large
tank, and have a very high profile are sporting some of the fancy Metal
Hallide lights underneath. They do produce a spectacular effect, but
don't forget that they have a spectacular price tag and you also get a
sepctacular hydro bill as well. :) You could have a look at such things
in some of the better fish stores, hydroponics stores, or garden
nurseries. Leave the Visa at home!
