T8 lamps are tubular fluorescent and LED bulbs, where the “T” stands for “tubular” and the “8” indicates a diameter of 8/8ths of an inch (1 inch or 25.4 mm).

They are energy-efficient, widely used in commercial, industrial, and home settings for general lighting, and are available in various lengths, wattages, and colour temperatures.

Modern T8s often use LED technology to further reduce energy consumption and are designed as direct replacements (retrofits) for older fluorescent tubes.

Key characteristics

Shape and size: They are linear tubes with a diameter of 1 inch (25.4 mm), making them thinner than older T12 tubes.

Technology: They can be either traditional fluorescent or more energy-efficient LED.

Energy efficiency: T8 lamps use less power to produce bright light, especially LED versions, which can lead to significant energy savings compared to older technologies.

Applications: They are commonly used in offices, schools, retail stores, and homes for general and task lighting.

Compatibility: They are designed to fit into existing fixtures, and LED T8s can often be installed as a direct replacement for older fluorescent tubes.

Why they are popular

Cost-effectiveness: They offer a good balance of performance and cost, especially LED versions that reduce energy and maintenance costs over time.

Reliable lighting: They provide consistent and reliable illumination suitable for long-term use.

Upgradability: They are an easy way to upgrade existing fixtures to a more modern and energy-efficient standard
