Description
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.
Sylvania's model 21781 light bulb uses 32W of power, with a brightness of 2950LM lumens. It fits a Medium Bi-pin base, and produces a cool white light. With typical use, it lasts about 30000 hours on average before requiring a replacement. This product is sold in multiples of 30. It comes with a standard manufacturer's warranty, and its UPC is 046135217814.
