Medium base, referred to as Edison or standard base
Torpedo Light Bulbs have a standard Edison base to fit many styles and types of light fixtures. Frequently used on antique lighting as slim profile easily slides into chimney. The space between bulb and chimney provided by this slender style, resists heat build up which can occur when using normal-shaped light bulbs in tight areas. Use on floor and table lamps, chandeliers and wall sconces.
