The resistance of the old-type incandescent lamp, when cold, is much less than when lighted, so when connected to half its design voltage, it will be something mildly unpredictable. Fluorescent lamp and its ancillary circuits that are designed for 220 volts will probably not light at all at 110 volts, but cause the igniter and ballast overheat instead. Some CFL products are designed to drive the lighting element at the same voltage no matter what the input is, so it will draw more and not less current. A LED might not light up at all, or it might give 50% luminosity. All depends on the kind of lighting fixture and luminous element we are discussing. Direct application of Ohm's law will not work.
