I think Im gonna go with these. $46 after coupon and comes with zipties and double sided tape for install. They are 15.35" long so will be perfect for lining the underside of the shelves. Also step dimmable.

Installed on this 18" x 18" shelving. I am afraid 24" x 24" wouldnt fit and apparently 23" x 23" isnt a standard size for some reason.

The 80 watts the 8 strips make together plus the 75 watts triple goose neck led should be more than enough for a clone/seedling/mother 2x2 tent.
