Red lens. by Wanderingval :-)
Red lens inside the Umpqua Lighthouse. Oregon.
The Umpqua Light shines through a first order Fresnel lens made of 616 glass prisms handcrafted in France and weighing two tons. It is a beautiful display of fine craftsmanship and produces a spectacular colored light show at dusk. This is especially true if there is a very light mist in the air. The light rotates out to sea and on the trees behind it on the landward side.
The light shines 24 hours a day. As you enter Umpqua Lighthouse State Park, down a winding road, the light's rainbow beacon rotates through the tall pines with alternating white, white and red beams. The lens assembly was originally turned by a clockwork mechanism much like a grandfather clock, powered by a huge weight which had to be wound up by the lightkeeper every four hours.This motive power 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 high powered 1,000 watt electric bulb. A spare bulb is mounted on a panel, which automatically moves it into place should the first one burn out. In November of 1983 the old chariot wheel mechanism that rotates the light broke down. The Coast Guard promptly installed an airport beacon on the tower and made plans to remove the original lens. Local residents launched a storm of protest until the Coast Guard relented and repaired the rotating apparatus. The lighthouse was restored by the US Coast Guard and is maintained by them.
