I'm not an electrical genius so I won't comment on usage costs, (especially since I suspect that MH's are less energy effiecient. But I also suspect thats due to start up energy usage primarily).

Actually MH lighting is More energy efficient..here is something to chew on. Think about it, put 400W of ANY florescent lighting PC/VHO/T5 , T8 or T12 & you throw in one 400W of MH, which one will produce more PAR per given area? YEP, MH, this is why MH is used for SPS, clams etc, they have more PUNCH per watt of power. Lets not confuse power consumption with light efficiency, if you add an electronic ballast to the equation you will get maximum efficiency per watt Period, there isn't anything better. I do agree wholheartly about the fact that you can thrive a tank without MH, & I also agree that supplementing is the best way to go, start out your lighting with fluorescents them MH & then reverse the process for evening light.
