These are bulbs that were actually used in the lens at the lighthouse. The larger bulb on the left is a Metal Halide filament used circa 1968-70. The smaller rectangular bulb on the right is a T-20 circa 1950s. Both light bulbs are 1,000 watts and generate 1.3 million candlepower when magnified by the 1st order Fresnel lens.
