So you can remove the suspension wire completely and have the fixture "bare", so to speak?@saf1 do you mean the flat top of the fixture itself? it has 4 tiny holes in which live one-way cable pinch connections. So cable goes in and wont come out unless you depress the little barb sticking up. Very slick.
Honestly, if I was going to attach these directly to 80/20 I would 3D print a bracket or otherwise fabricate one.
@xabo min height above water is 6" and you just get more spread (but less par and more light spill) the higher you go above that. I think mine are at 10" now.
