Well my computer area is now lit by the other (still 2-lamp with the Universal Therm-O-Matic ballast) fixture from my school. The setup is pretty much a 1X4 troffer-cum-shoplight since I have suspended it with Gangion (A type of thick, heavy-duty string used for fishing gear) from the sloped ceiling. In acutality, credit could go to someone else I know who had the (literally!) brilliant idea to suspend them. I thought, "That's a really good idea actually!" and I plan to do the same to the other (3-lamp) one eventually. Where that one will be going is at a right angle to this one so it'd be "flat" on the sloped ceiling but suspending is so much easier, especially when installing a light by yourself (This one already took enough ingenuity to hang and took about an hour and a half of creativity (My installations always take forever; especially fluorescent fixtures; the only time I didn't suspend fixtures was between ceiling joists in an unfinished ceiling so I stuck some 8 penny nails in the joists to balance the fixtures on while fighting with the screw gun and probably muttering profane words under my breath). But anyway back to this light...like I said it required some creativity to hang (I actually took some pictures of the light half-hung, sitting on a cardboard box, then an old Philips bass subwoofer, while I was in the process...it did look pretty ridiculous! Once I got both ends up I discovered that of course having a nice heavy magnetic rapid start ballast off to one side of the fixture affected it's balance...so then I had to take one end BACK down and move things around, then it was OK but it was out of square if you will; this light is actually a little on the flimsy side being a troffer, so I had to add some other wire (Old ballast leads actually) to the corners in a very silly-looking way (A typical Andy install I must admit, mine always are a little bit too creative and dangerous-looking.) The worst part, I will say, was trying to install the lamps afterward...we all know troffers are a royal pain to relamp anyway, as are suspended fixtures...how about both! The current lamps are a pair of May 1979 warm white GE Mainlighters manufactured at the Jackson, Mississippi plant. Is a lamp NOS if it has mercury condensation or is it used? (I know I've fired this particlular pair up before but do you guys think they were never used before that?) Regardless I bet they'll last for years and years in normal residential use. The ballast is quite buzzy upon startup, getting even LOUDER at first, then quiets down. This one doesn't do the annooying flicker thing as much on one of my generators whereas that Advance Kool-Koil flickers too much to be working under...this one flickers slightly but nothing I can't ignore. Ideally I'll find a F72T12 slimline someday for this spot...it will fit PERFECTLY! Where the other light is going would be nice to have a F96T12 there someday.
