Found an old battery-powered halogen table lamp in a disassembled state. It used to have a small 12-v lead-acid battery in its base but the charging circuit had fried when I fed the wrong power supply into it. So I rewired it to work from an external power source, such as the backup battery from a security system I no longer use.
There's an IR remote control for it somewhere & the brightness control no longer works, but the switch can turn it on & off.
So it's another source of illumination in blackouts, which are likely to be more prevalent when one of the state's oldest coal-fired power stations is decommissioned early next year. Wanker politicians say "there's a reduced demand once the vehicle manufactures shut up shop next year, so there won't be any blackouts."
I say bullshit to that theory.
