I quickly made this just a few minutes ago and hooked it all up. Process took about 20 minutes including removing the old lights and installing the xr30. I ran 2 kessil a80’s on this nano so i just used the cheap goosenecks for them $50 solution vs a $100 rms mount. This post was about using them on my 100 gallon build and not this 20 gallon but i can atleast start using the light now instead of months from now. I screwed the kessil bracket into the sides of the radion plastic frame using 1” wood screws with the light taken apart to ensure i didnt hit anything inside the light and boom it works like a charm. I would say though this will probably on work on a standard 20 gallon tank just because of the length of the arms and mounting height. It just so happened to work perfectly.
