LED advice

[bkelly]

Hi
I am looking into a LED fixture for my tank. Our electricity bill has really gone up so this decision may help significantly. Am I on the right track thinking my current fixture ( six T5s and Two 250 MHs) with a PFO magnetic ballast , plus running a chiller (1/2 hp with a 1200 GPH pump) would be using lots of power and what would you think by putting a LED fixture that could support my tank full of SPS. tank dimensions 4feetx3feet x2 feet. What sort of fixture do you suggest . Is this a direction that would really lower my electricity needs?

- Guess I need to know if Id be able to stop running my chiller and is LED efficient on electricity over T5/MH plus what type to buy.
Thanks for any help.
