Fairy lamps are glass lamps which were lit using small candles. They came in many styles and were marketed as nightlights, lights for nurseries, and home security devices that would deter possible intruders. They were also utilized occasionally for vaporization to treat respiratory conditions.
Small, squat candles were wrapped in paper and placed inside the lamp or lamp dish with a small amount of water in the bottom. This would allow the contained candle to burn for many hours without having to be watched. This made fairy lamps a safer lighting device than oil lamps or taper candles.
They were highly popular by the late 19th Century around the world. Queen Victoria was a big fan of fairy lamps and it was rumoured that she purchased over 1,000 of them in the late-1880s to decorate the royal home.
Fairy lamps were useful for lighting dark areas of the home for lengthy periods. They were safe to use, beautiful to look at and very affordable. These qualities fueled their popularity.
