At work so cant show pics, but can answer. One of my lil brass pieces was loose so I popped it open to tighten it, which broke the sticker seal for the warranty. But yes they come out.
I mounted mine on top of my canopy to make the height adjustable.
I used the brass fittings kind of weird. I made a boxed frame from 1x2s slightly larger than the lights and used an Lbracket with 2 holes in it. Mounted 4 of those on the frame I made, then took cut two pieces of threaded rod and ran it between the brass fittings. The height can be adjusted about 4 inches more if u use larger brackets.
Mine were the 2in ones. You can use either hole to go higher and to go lower I just flipped the brackets to point down into the tank.
It is sturdy as hell and if ur canopy has thicker wood on top than mine did u wouldnt need the frame. I like the frame so I can take off everything in pieces. Lights, lid, then full canopy.
