La-Tee-Da!
Unlike regular candles or oil lamps, instead of spreading the fragrance with an open flame, La-Tee-Da! lamps use a uniquely designed stone-wick that burns alcohol-based fuel that is fragrance enriched. This fuel burns using a special catalytic process that creates a combustion that is only one third the temperature of that of a candle.
