I have a dual 8 foot fluorescent light fixture in my basement (F96T12/C50, single posts, 75W x 2). I want to install some ceiling tiles, incl. T-supports, hangers, etc. So I have to pick the height and location. Currently the lights/fixture is the lowest height level in the room. It is attached directly (perpendicular) to the floor joists (2x10s), screwed directly up against them. Its positioning is correct and it is not practical to gain more height than the bottom of these bulbs.
The fixture is a sealed sheet metal rectangle. It is wired downward from an octagon box above, which is screwed to one joist. I am not interested in this part. There is no reflector shield on the top/side of it. The 2 bulbs are just exposed. I am planning on putting a cover/shield/ flat piece of plastic into the ceiling tile grid. I am wondering about the proper way to do this. I am not sure whether to make a wooden surround frame (shroud), and put my cover in it, and ceiling tile grid built around it, or if I can make the plastic cover part of the ceiling tile grid T-support structure. But is it possible to build a T-bar grid for the cover into the main grid structure (same level)? The matter is what is safe/ to code w/r/t materials/gaps/methods. I guess there is not much heat.
The entire room is 68" wide and the 5" wide fixture is 38" and 30" to the sides. (small direction of room).
The entire room is 164" long and the 96" long fixture is 82" and 84" to the ends. (large direction of room).
The room is a rectangle, except there is a J-shaped duct to build completely around in one quadrant. I'll use the 2x4 foot ceiling tiles; the rectangleness of the ceiling tile is installed perpendicular to the rectangleness of the room (right?).
Anything helps, Thanks
