During World War II, especially along coastal areas, periodic blackouts required all street lights to be turned off, cars and truck lights to be dimmed, and lights turned out in homes so that enemy bombers or ships wouldn’t have light to identify targets.

In order to be able to have low levels of light in the home, blackout lamps were developed.

This bulb has a mirror coating on the inside to help focus the light to the bottom.
