Very good points. My initial concern was for too much lighting from the Ray II and the fact that I couldn't dim it without suspending it or raising it off the tank, which wont be an option. This was the only reason i considered the Fugeray. I ordered the II and will see how it rolls in the beginning. At this cost I can add a second of either model if we feel under lighted with the initial Ray II.
