Kitchen has florries under the cupboards. Downlighters lighting the rest

The only CFLs here for some time have been in the attic, and for the
couple of minutes per month they're on can stay that way.

So a carrier bag of incandescent G23s, GU10s, MR12s, SES candles and
"free" CFLs is waiting for chucking out, all that's left in the spare
box are two oven lamps and a one halogen BC22.
