LED lighting requirements for a 180?

[yellowtruck75]

I am interested in setting up a 180 long tank and I want to use LED but have no idea about what it would need. I want to be able to keep clams on the sand bed and have no restrictions on other corals.

Thoughts?

If you want to save money and can do a DIY that would be the way to go because you'll have many options.
Or the AI's are good but you'll be spending around $1200.00
