This lengthy, comprehensive article provides information about “LeeNer,” a product which provides a way to light electric candles for Shabbat in a manner that is considered halachically acceptably by many authorities of Jewish Law. At times, the ability to fulfill the mitzvah (commandment) of the lighting of Shabbat candles by kindling live flames is impractical, such as when people find themselves in a hotel, hospital or army base, places in which the lighting of fires is prohibited. Due to the length, detail and highly technical content of this article, it is relevant to those with a strong background and interest in the Halachic system, as well as a specific need for this product. The Zomet Institute is a non-profit, public research institute dedicated to seamlessly merging Halachic Judaism with modern life and technology. Â
