The year is 1942. On the Zook farm near Honey Brook, Pennsylvania, this unnamed Amish farmhand is mending a harness. He is using daylight because the electric lighting has been
disconnected for religious reasons. In John Collier’s photograph, the lamp remains in its socket. Although light is used ceremonially in many beliefs, candlelight in Christian churches and all
forms of light during the Hindu festival of Diwali, for example, there are other religious rulings on its use. Many Orthodox Jewish authorities prohibit the turning on or off of electric lamps on
Shabbat, although a special lamp that remains on but can be blacked out may be used. In other areas of life, the most effective energy-saving lighting control remains the off switch.
