Can someone also please explain what the hyper violet bulb surcharge is about, do I need it, how would I benifit by having it, why is there an additional cost for this lamp?.

Also can anyone tell me what the light spread of the units are as my tank is 5 x 2 x 2 so what would be the best way to light it with no dark areas, do we know yet how close they can be to the water surface and what mounting kits are going to be available for the units.

Sorry if its a load of questions but as I'm probably going to spend 2k on these lights, I want to know all I can about them up front
