The new Radion mounts, mount to the back of your tank No need to hang anything from the ceiling.
By the time the Radion "goose neck" mounts are available for sale we should have the information about the specs, control, fit and finish of the RS new LED only hood.
As I said earlier I would prefer to just wait on the new LED RS hood if it answers all the right questions for me to make it worth waiting another year to get one.
If not, goose necks will have to do. I want to have the control that I can get using my APEX with the Radions and the jury is still out if the RS LED's will have the kind of options and controls as well as the ability to upgrade lighting as technology changes in a timely manner once they are released. Hopefully RS will finally start addressing some of these concerns before Radion releases the new mounts in Aug/Sep timeframe. We should know soon if it's going to happen.
