395nm is a uv light spectrum. Corals will utilize this spectrum somewhat and lately there has been some research coming out that it helps with sps growth. The new generation radions and ai led units use a couple of uv nodes per puck.
How ever if you are asking if the uv spectrum alone can support coral then the answer would be no. Full spectrum is the best way to go for reef tanks.
