A single Radion at 8" off the water over a 14" deep tank will light the entire tank. However, Radions don't cover 2' spreads as well as some other led fixtures due to the tight grouping of the leds and that the light won't get the benefit of a 24" deep tank to spread out. You may find the outer edges of the tank are not as well lit and may not be acceptable for sps corals. But you are probably right at the ragged edge of enough. If you can raise the fixture higher off the water, you will get better end to end coverage.
