Lighting Advice...

[Mr Cob]

I have just purchased an Ice Cap 660 Ballast with 4 VHO/T12 48" bulbs at 110Watts each. All 4 are 180° internal reflectors giving 40% more light intensity. 2 are Super Actinic, 1 Actinic White 12k and 1 10K.

I have a couple of questions:

1) The total equals 440 watts (it's actually like 50watts more because I have a corallife 50/50 too), does the 40% extra actually raise my watts per gallon?

2) I have a 120gal with about 125-150 pounds of live rock, fish and some softies...with this lighting setup what all can I keep in regards to corals? Is this enough for SPS?

3) How much help would reflectors be for the bulbs? They advertise that the refelectors increase 90% light intensity...is this really true?

Thanks for your time...I do a lot of research outside of Maast.org but it's priceless to be able to ask experienced hobbyists!
