A sympathy lamp is a device used to produce bright and steady light continuously for a long-lasting period of time.


Sympathy lamps use sygaldry to sympathetically convert ambient environmental heat into light.[citation needed] The typical lamp glows with a deep, red light,[1] though an artificer may also make blue and yellow lamps.[citation needed] The lamps are brighter than gaslight, steadier than candles or lamps, and lasted nearly forever.[1] Although the light from these latter lamps are easier upon the eyes, they require hazardous reagents such as bone tar or toxic transporting agents in their manufacture.[citation needed] As a result, such lamps are quite valuable and therefore very expensive.[1]

Because of it high costs, very few people had ever heard of it or seen one. Baron Greyfallow has one in his library at his manor.[1]
