Types of Tube Lights
Tube Lights also known as linear light bulbs, are frequently used in office buildings, kitchens, work spaces and commercial installations as well as homes, with varying sizes and brightness levels. This guide reviews the different types and configurations of tube lights, both fluorescent and LED, so you can choose the
best tube lights for your light fixtures and other lighting needs. While there are multiple types of LED and fluorescent tube lights, the three most common are T12, T8 and T5. The terminology comes from “T” for “tubular” and the diameter of the bulb in eighths of an inch, so “T8” represents a tube of about an inch.

Bulb Sizes
as the power in watts and the amount of light given off, measured in lumen output. The color-rendering index, or CRI, represents the quality of light output, with 100 being equivalent to natural sunlight.
T12 lights have a regular width compared to the other lights. Diameter is 1.5 inches Length is 48 inches Energy to emit 2,500 lumens is 40 watts Durability is 10,000 hours CRI is 62
T8 lights have a thin width Diameter is 1 inch Length is 48 inches Energy to emit 2,500 lumens is 36 watts Durability is 10,000 hours CRI is 85 .
Bulb Temperature
T5 lights have an ultrathin width Diameter is 0.62 inches Length is 45.2 inches Energy to emit 2,500 lumens is 28 watts Durability is 15,000 hours CRI is 85.
Fluorescent tube lights are low-pressure mercury-vapor gas discharge lamps that use fluorescence to produce visible light. Fluorescent tubes require an electronic ballast to regulate the flow of electricity.
LED tube lights, which use light-emitting diodes to provide illumination, are increasingly used to replace fluorescent lights. Compared to fluorescents, LED lighting lasts longer, is more energy efficient and uses no mercury. Instead of a ballast, they regulate the electrical flow with electronic components that make up the LED driver.
