Fluorescent light bulbs, commonly referred to as "tubes," come in linear, circular, and u-shaped bulbs that require an external ballast to power. They are ideal for use in offices, warehouses, auditoriums, and other areas that need a large area of light. Because they produce about 75% less heat than incandescent bulbs, they keep indoor areas they light relatively cool compared to high-wattage, traditional lights.
