Abstract

An institutional lamp includes several features to enhance lamp longevity and safety in an institutional setting. A diffuser/guard assembly fully surrounds the lamp bulbs to prevent casual disassembly or inadvertent contact with the bulbs. An auxiliary socket is provided that can be conveniently used to power other devices. A night light bulb is included and is also located within the diffuser/guard assembly. When so located, the lamp continues to provide a natural appearing illumination when the night light feature is used. An easy to use rocker switch is provided to enhance user operating convenience, and a durable, plastic lampshade avoids the types of damages frequently suffered by cloth shades. Preferably, the lamp is constructed of heavy, durable materials to improve durability. However, the lamp is styled and decorated to have the type of inviting appearance commonly associated with lamps intended for use in the home.
