First introduced in the 1890s, electric pharmacy-style lamps easily provided a direct downward light their gas-powered predecessors couldn't—imagine trying to turn an open flame upside down. That targeted light, combined with adjustable arms and beam-focusing dome-shaped metal shades, made them ideal for task lighting in pharmacies, hospitals, and factories. By the early 1900s, the versatile cast-iron- or brass-bodied lamps began migrating from the workplace to the home office, den, and bedroom. Today, pharmacy lamps still bring a utilitarian yet attractive glow into the home, and in a growing array of finishes and configurations. Here, 16 of our favorites.
