We had numerous power cuts here, it was a regular event. The last time we had one my daughter went to the local corner shop (which wasn't affected) and bought 2 dozen candles, 2 dozen tea-lights, 3 of those enormous decorative candles and new batteries for the big torch. The next day I bought a new wick for my brass oil lamp and some paraffin for the fuel.
That was 18 months ago and we haven't had a power cut since.
