A solid state update to the original fresnel-lensed whale oil wick lamp, below. Just before sunset on March 1, 1874, the keepers lit the lamp in a revolving fourth-order Fresnel lens sending forth brilliant beams of light across San Pablo Strait.
It was surprisingly non-blinding when I looked right into it from 1 foot away.
