There are some great utube videos on building LED light modules. You would likely want 2-3 modules mounted front-back versus side-side. Gives you the option of a better mixture of actinc and white lights as well.
I spent so much money on truelumen pro strips. Had 6 - 12" strips over my nano. Dont buy them. They suck for corals. My corals died. I was only able to keep zoas with no growth. I ended up upgrading to a 120 watt panel and using the strips for supplemetal lighting.
