my old elementary school in Atascadero, California had t8 troffers in the classrooms, some two lamp, some more in the modular classrooms that were added later. HPS recessed square fixtures in the hallways, t8 single-lamp fixtures in the bathrooms, HPS wallpacks, a few strip lights, also t8, and everything flourescent was instant start. I am the same age as Mike, and I last went to that school in 2008. There were more fixtures but I'll make a list of what I remember and maybe make another post. My new school runs entirely off a generator, since I live in a remote Alaska town of about 30 people. Anyway it is entirely f40t12 and a few HPS lights outside and in the gym. I gave the school a bunch of vintage norelcos and GE mainlighters, and the first norelco went in recently. ( I an 14, but help maintain the lighting.) The school has t12 surface mounted 1x4 troffers inthe original 1970s single classrooom(it's a small school) and a few wraparounds in the hallways. The 1984 addition has exposed striplights with reflectors on the top half to direct the light downward, and these weird wraparounds in the classrooms that are two lamp and have opaque lenses that are white plastic. The only thing that looks ugly is that someone did spot replacement and has regular cool whire lamps mixed in with GE "chroma 50".Looks strange. Also, when ya first turn them on, they buzz loudly and the 34 watt lamps start out dim and ugly. No, they are not Alto, but GE wattmisers new enough to have the hg logo. They are being replaced by the janitor and I with true 40 watters. Much better! The school has a combination of chroma 50 with the old GENERAL (GE) ELECTRIC etch, wattmisers that are not ecolux but have the big meatball, true value lamps, westpointe lamps, Sylvania cool white plus, and we just atarted on the Norelcos that the city hall was throwing away when they went to t8. Everything, and I mean everything is RAPID START!!!!! The restrooms have cool lights, will try to get a pic made of prismatic diffusers and wooden sides. The ballasts run the lamps in series I think, because when one lamp goes bad both go out or dim, sometimes only one staying lit. Sometimes when a 34 watter dies, it will glow dimlty at one end, (because the electrode on that end is okay?) Anyway, I am proud of this installation!
