would you like to add them? i can help you with that, there is a very simple way to do this. recently i ordered several t5 bulbs of the net, they came in these cardboard tubes about 3in diameter about 5ft long. so i had an extra t5 ballast i wired it up cut holes for the tombstones and covered the surface with hvac tape to make it reflective, very lightweight, and better than hanging all that metal! you could probably get the tubes at a packing store or hardware store, i just use screw in hooks to suspend it with chains screw right into cardboard, it is surprisingly thick. as far as fire, well flouros arent know to have this happen and i dont think it is a major concern, i could see where hid and cardbourd or incandesant, but the heat form fluoro isnt shit.
attic shit.. its not hot up there?
