I know next to nothing about Hannukah so I hope you'll be patient with my question.

If Hannukah celibrates an oil lamp that burned for eight days with only one days worth of oil - why are candles burned? Why not an oil lamp ? Or is an oil lamp burned too ? Why and when was the switch made from a lamp to candles ?

If anyone would like to explain some of the other traditions of Hannukah I'd love to learn more about it.

Thanks.
