label: Description (Brief)
content: Incandescent lamps dominated the electric lighting market for over a century. Despite poor energy efficiency, their versatility and ease of use resulted in their almost universal adoption for applications ranging from the very large (searchlights and airfield illumination) to the microscopic (surgical lamps). Miniature lamps that could withstand a high-vibration environment—such as in a vacuum cleaner—constituted a special area of lighting technology development. Designed for a self-service store, the packaging for this unit also demonstrates features such as an asymmetrical design (for reducing the size of shipping boxes) and a punched hole (for displaying the product on a peg-board) useful in a retail environment.
