I have been using 2 ea Mitras LX6100HV lamps since september 2012 on my 390 litre Deltec tank.

I have been very satisfied with these lamps, and my sps thrive excellent under this light.

I do now start to think about my next upgrade, a tank with the following measures 150x75x55 LXWxH.
My plan is to use Three Mitras lamps
If possible I would like to avoid having the lamps hanging from my ceiling each separatly.

Do you in GHL have any frame or rail system that can be used to mount such set of three lamps?
They will have to be mounted 90 degrees on the length of the tank to reach maximum coverage

If no commercial railsystem, does anyone have any good ideas of a visual well looking system that can be made/used?

I need something that looks nice as this will be an open installation with everything visual in my living room. A high WAF (Wife Acceptance Factor) and also my own goal of getting something that looks nice will be important.

Another question; is it OK to combine my two existing lamps With a 6200 Version to get some cooler light colour, or will that be of less importance or create strange allover colours?
