The GE Circlite and similar fluorescent circline adapters were the first form of energy-saving lighting to fit in a standard bulb socket. They're difficult to assemble, too large to fit in many lamps, and take a long time to turn on, but produce bright, pleasant light and use much less power and produce much less heat than a standard incandescent bulb.

Most people abandoned floppy disks long ago, but vintage computer enthusiasts still have a use for them, especially older sizes and densities. New floppy disks aren't being made anymore, so is it a good idea to buy used diskettes? I bought a lot of 3.5" 720K diskettes in unknown condition, looked at the old files that remain on them, and reformatted them.
