Looks very promising. Only draw back I can see is that the plasma lights seem to be much more yellow than people like since everybody seems to be after the blue. If they get bluer they can gain a market I am sure.
I'd love to see some pics of the test units over coral
It's got to be an old post though since another company has already been marketing plasma for awhile now (I think they're called SeaView or SeaVision or something like it)
