Mitras 6xxx pendant vs Mithras light bars

[Gunther]

from your answer I thought you are using light bars

I have one, but my tank is´that long so I use some kind of Z-holder

I would not recommend linking two or more light bars with a "self-supporting bridge". The weight of the light bars where one links to the other would be too heavy and may create some sagging.
