An LED tube light is a tube-shaped lamp typically found in linear fixtures. The most common tube light, T8 tubes, fit into fixtures such as utility lights. Other LED tubes, such as the U-bend, fit into specialty fixtures.
LED tube lights last up to 10 times longer than other light bulbs. Some models last up to 50,000 hours.
LEDs perform better with instant on technology, requiring no warm-up or cool down. They also offer more lumen options than other types of bulbs.
LEDs require less wattage to power, which saves energy. Energy savings translate to money savings.
LED tube lights use a driver instead of a ballast, and make no humming or buzzing noises.
The "8" denotes the diameter of the bulb, in increments of 1/8 of an inch. A T8 bulb measures 8/8 inches, or 1 inch in diameter.
