Adequate spectrum for corals?

[Spikehs]

Hey,

I was thinking of getting this used system with the following specs:

2 X 250 Watt 4300k MH
four 55 Watt 10K/Full Spectrum Compact fluorescent w/ballast

for 200bucks

would this be enough lighting with proper insensity to go over a 77gal tank? because i was a little worried about the 4300k halide bulbs...but there is 4 55 10000k power compacts. Any input would be appreicated.

Thanks
