how does one dim??

[that novice guy]

i will be making a new light that would be fully dimmable it will consist of 24 cree 1:2 ratio and 2 48 inch vho bulbs and i would be using the coralvue 660 dimmable and how would i dimm it? with the use of an neptune controller the tank is only 4'L 1'H 2'W

some other questions
*what bulb should be used
*how high
*relectors or no reflectors
*how do i connect neptune to drivers and ballast


and its all going on this tank or poor kids build :wink:
