| has gloss | eng: A Shabbat lamp is a special lamp that has movable parts to expose or block out its light so it can be turned "on" or "off" while its power physically remains on. This enables the lamp to be used by Shabbat observant Jews to make a room dark or light during Shabbat without actually switching the electrical power on or off, an act that is prohibited during Shabbat. It's prohibited because flipping an electrical switch is considered to be lighting a fire, due to the tiny electrical sparks. |
