Well If you go by the old saying "there' no such thing as too much light", the obvious choice would be the two 400's.
 However, there is a qualifier, what is in the tank"

Holy cow 2 X 400W for a 77g tank is a lot! Unless you are upgrading to a bigger tank then ignore this. I'm sure you have thought of it but you will definately need to take heat into consideration. I have 3 X 400W over my 230g and need a fan blowing over the sump/fuge to control heat. A chiller is definately on my shopping list before next summer. My tank is 31" deep (can you say PITA for cleaning) and I still have to be careful how I place coral as it will easily bleach

here is a great link to look at in respect to lighting in a reef aquarium...I was going to go with 3-400 W in my 24"deep 150G tank...it made me change my mind to 1-400 in the middle and a 250 on each side

Well I got the dual 400 watt ballast for a reasonable price and could not turn it down. Down the road I want to upgrade the 77 to a 150 or 250 So I figured why not get the light I want now.
Since I probably wont run the 400 watts all day should I also go with some VHO? I want to get into some SPS and LPS eventually. I already have dual fans in my canopy one sucking air in and the other discharging. Do not have the MH going full time yet, as I still have my PC going. Jim
