T5 and T8 are two common types of LED tubes that are used as replacements for traditional fluorescent tubes in lighting fixtures. While both types have similar benefits of energy efficiency and long lifespan, there are several key differences between them.
1. Size and Compatibility: T5 tubes have a smaller diameter of 5/8 inch, while T8 tubes have a diameter of 1 inch. This means that T8 tubes cannot be used in fixtures designed specifically for T5 tubes, as they will not fit. However, T5 tubes can be used in fixtures designed for T8 tubes by using an adapter. It is important to check the compatibility of the fixture before choosing between T5 and T8 tubes.
2. Light Output: T8 tubes generally produce more light output compared to T5 tubes. T8 tubes typically have a lumen output ranging from 2600 to 3200 lumens, while T5 tubes have a lumen output ranging from 2000 to 3000 lumens. The higher light output of T8 tubes makes them suitable for areas that require bright illumination, such as offices, retail spaces, and warehouses.
3. Efficiency: Due to their smaller diameter, T5 tubes generally have a higher efficiency compared to T8 tubes. This means that T5 tubes can produce the same amount of light output while using less energy. T5 tubes typically have an efficiency of around 100-120 lumens per watt, while T8 tubes have an efficiency of around 80-100 lumens per watt. The higher efficiency of T5 tubes makes them a more energy-saving option for lighting applications.
4. Lifespan: Both T5 and T8 LED tubes have a longer lifespan compared to traditional fluorescent tubes. Generally, T5 tubes have a lifespan of around 50,000 hours, while T8 tubes have a slightly longer lifespan of around 60,000 hours. This means that both types require less frequent replacement, resulting in reduced maintenance costs.
5. Cost: T5 tubes are generally more expensive than T8 tubes due to their smaller size, higher efficiency, and compatibility with specific fixtures. However, the initial cost difference is often offset by the energy savings and longer lifespan of LED tubes compared to fluorescent tubes.
In summary, the main differences between T5 and T8 LED tubes lie in their size, compatibility, light output, efficiency, lifespan, and cost. When choosing between the two, it is important to consider the specific lighting requirements of the space, the compatibility of the fixture, and the desired level of energy efficiency.
