Lighting advice? Do you mount them or hang them?

[fraggalrock]

I just got my 90 gallon tank with the canopy and picked
up a great light m/h 48 long at a great price,but it is so
heavy and I am unsure of how to mount it or what to do
any advice or examples is most welcome. I love the look
of the canopy and want to keep it and removed the back
off of it for cooling reasons but I still have not decided
on how to do this.btw it is heavy because the ballast are
built in.is there a way to do this where it looks good?
There is a pic of my tank under sherrys 90 gallon build
on the tank journal
thanks sherry

In my old tank, the mh fixture was on the tank, but that was really annoying bc it added heat, and greatly limited access to the tank.

I took a 2x4, painted it white, screwed it to the ceiling and connected the hanging kit to it.

SO MUCH BETTER.

no I have a new set up.

I have the Coralife 48" Aqualite Pro, and have it sitting on my tank with no problems.

How heavy is yours? Is it MH? I am not thinking its MH, as the ballasts would NOT be in it.

Screwed some phenolic strips to the lights (for thermal break) then the strips onto my canopy.

i hung mine much easier to remove canopy

canopy is 8 inches high on front and sides and just used a 2x4 across the back so the light is a 1/2" higher than the 2x4 so the canopy slides right out the front

It is a MH with built-in ballasts. Much heavier than Coralife Aqualight Pros.
