I wouldn't give my neighbour candles as trade goods in case he burnt his house down and the fire spread to mine.

If you are a good capitalist, you could try LED torches, Eneloop batteries and a solar-cell charger. (You keep the charger for yourself, of course, and offer a battery-charging service.)
