Inside the lantern room you find a large "beehive" optic that does not rotate and has red and white sectors. The primary and secondary light sources are two tiny bulbs, mounted on the plinth in the top centre of the photo [Photo: Ken Trethewey (2016)]

There are no circular "bulls eye" lenses in a beehive optic because it does not rotate. [Photo: Ken Trethewey (2016)]
