lumens per watt of energy put in, and seem to be available in
spectra that plants ( and corals ) appreciate.
I have had a 400 watt unit in operation over my reef tank for
quite a while and have not been visited by the DEA ( you would

bill each month. A 1000 watt setup would add $75 to my bill - and
that's the reason why I don't keep more high light plants inside.
