lighting question

[CLINT]

hello im fairly new to reefkeeping and have yet to get hard corals.Just curiousif anyone knows if 1 400watt 14000kmh is sufficient for a 72gal bowfront? my collection right now is mostly ricordea and zoo's but i have recently been forced to change lights due to major power surge in my house that wiped out old lights and pumps in tank.just dont want to waste any money on nice hard corals if the light is insufficient but i also cant afford another ballast and light right now so if i have to wait I will.any replie is greatly appreciated.
thanks CLINT
