Energy Efficient Lightbulbs

Anyone want any free energy efficient lightbulbs? I keep getting spammed with them by British Gas, Southern Electric, et. al., in a desperate attempt to prove their green credentials. Of course, it doesn’t work - I already have all I need and they are now piling up in the cupboard (here’s a hint: maybe that ain’t so green).

The law of unintended consequences is a bitch.
