The Umpqua Light shines through a 1st order Fresnel lens made of 616 glass prisms handcrafted in France and weighing two tons. The lens assembly was originally turned by a clockwork mechanism and powered by a huge weight which had to be wound up by the lightkeeper every four hours. This is now performed by an electric motor and monitored by sophisticated equipment, which notifies the Coast Guard station if a malfunction occurs. The original oil lamp has been replaced with a 1,000 watt bulb.
