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.

Satco's model S2908 light bulb uses 4W of power, with a brightness of 115LM lumens. It fits a Mini Bi-pin (G5) base, and produces a daylight colored light. With typical use, it would last about 5000 hours on average before requiring a replacement. It came with a standard manufacturer's warranty, and its UPC was 045923029080.
