3dreefing has mount that you can add to your radion with the ai blade.
I will be needing to add more lights as well in my tank and am planning to add 1 each of glow and grow to xr15. (I have lots of shading).
I am hopping someone will come up with tilting option granted one above allow you to tilt the led to some degree. You will still need rsm hanging kit. Seems to be the best option I. The market right now.
