Reduction of voltage, usually enough so light bulbs will still work to a degree but often not enough to power appliances. UK used to be 240VAC but then it got dropped permenantly to 230VAC but often even now applances and power supplies can be 220VAC. But during a brownout they cut it so you cannot power energy hungry gear like Washing Machines, Microwaves, Electric Ovens, TVs etc, but do get enough to keep some lights on.

In really bad events you can often interpret a Brown out as a warning of a Black Out to come.
