Sunblaster T5HO, 24" deep tank?

I am working on budget lighting for my 60 gallon and want medium lighting, but also to hang the fixture using bent conduit or some other attractive solution. I can't easily reach anything in this tank so a hanging fixture would make life much easier!

I also have access to a metal shop and am thinking of a simple curved or PVC gutter shaped reflector/cover. Either painted white or left metal on the inside.

So, assuming the lights are hanging 6 inches I'm 28" to substrate with either the super shiny Sunblaster reflectors or just my DIY one, how many bulbs would be best?

I also want moonlighting, so I plan on using timers, I think could chain the lights and still stagger the timing to have a mid day burst?

I attached pictures of the super cheap "full spectrum" eBay light and then the lighting using two daylight led floods in clamp lights.
The clamp lights hit the bottom, but I don't want to fight with them and they look silly.
