WebThe heated mantles in a gas lantern emit far more light than the flame of an oil lamp, therefore providing better visibility in a larger area. Mantles are chemically saturated fabric shells that, when heated by the lantern's flame, become a powerful source of white light—up to 300 candlepower, or the rough equivalent of a 300-watt bulb.
