Both for the effect and our of curiosity, I have begun using flame for lighting at home. In doing so I have become acutely aware of how expensive candles are. I now use only one to light a room most nights and have even begun collecting fat from the butcher so as to make own. But there are times during which it's completely dark that I need a light. I just flick a switch, grab my lighter light a candle and turn the light off and this has led to a lot of questions

What sources of lighting were there, where and when and who used them? How did the cost and risk of lighting influence everyday life? Any recommendations as to where can I learn more about lighting prior to electricity would be greatly appreciated.
