LED fluorescent tubes, also known as LED replacement tubes or retrofit tubes, have certain general specifications that need to be considered when choosing the right product. Here are some typical specs you should be aware of:

Tube Type: LED fluorescent tubes come in various types such as T5, T8 and T12, which refer to the diameter of the tube. Each type has a specific diameter, so LED tubes must be selected to match existing fixtures.

Length: LED fluorescent tubes come in different lengths ranging from 2 feet (0.6m) to 8 feet (2.4m). Common lengths include 2 feet, 3 feet, 4 feet, 5 feet, 6 feet, and 8 feet. Choosing the right length to fit your existing fixtures is critical.

Wattage: LED fluorescent tubes come in different wattage ratings, usually between 9 and 30 watts, depending on the specific model and manufacturer. Higher wattage generally indicates brighter light output.

Lumen Output: Lumen output refers to the brightness or intensity of the light produced by an LED tube. It is measured in lumens (lm). LED fluorescent tubes typically provide lumen output from 800 to 4000 lumens or more, depending on wattage and the specific product.

Color temperature: LED fluorescent tubes have different color temperatures, which determine the color appearance of the light. Common color temperatures include:

Warm White (2700k-3000k): Provides a soft, warm, yellowish light similar to traditional incandescent light bulbs.
Cool White (4000k-4500k): Provides neutral white light and is commonly used in offices, retail spaces and commercial applications.
Daylight/Natural White (5000k-6500k): Produces a bright, cool white light very similar to natural daylight.
Color Rendering Index (CRI): CRI measures the ability of a light source to accurately render colors compared to natural light. The higher the CRI value (usually on a scale of 0 to 100), the better the color rendering. LED fluorescent tubes typically have a CRI value above 80, with some high-quality options reaching a CRI value above 90.

Beam Angle: The beam angle determines the spread of the light emitted by the LED tube. It represents the angle between two points where the light intensity falls to 50% of its maximum value. Common beam angles for LED fluorescent tubes range from 120 degrees to 180 degrees.

Dimmable: Some LED fluorescent tubes are dimmable, allowing you to adjust the brightness with a compatible dimmer switch. If dimming functionality is required, it is important to check product specifications to ensure compatibility with the dimming system.

These are general specifications usually associated with LED fluorescent tubes. However, it is important to note that specific products may have additional features or variations depending on the manufacturer and model. Always refer to the manufacturer’s specifications and guidelines for accurate and up-to-date information on the LED fluorescent tubes you are considering.

LED T5 and T8 lamp tubes are both types of linear fluorescent replacement lamps, but they have some differences in terms of their dimensions and electrical specifications. Here are the key differences between LED T5 and T8 lamp tubes:

1. Diameter: The primary difference lies in their diameter. T5 lamp tubes have a smaller diameter of 5/8 inch (15mm), while T8 lamp tubes have a larger diameter of 1 inch (26mm). This size variation affects the compatibility with fixtures designed for a specific tube diameter.
2. Length: T5 and T8 lamp tubes are available in different lengths, ranging from 2 feet (0.6 meters) to 8 feet (2.4 meters). However, the length options may vary depending on the manufacturer and specific product lines.
3. Wattage and Light Output: T5 lamp tubes typically consume less power compared to T8 lamp tubes. They are generally more energy-efficient and offer higher lumen output per watt. However, LED technology has evolved rapidly, and there are now high-efficiency LED options available for both T5 and T8 lamps.
4. Ballast Compatibility: T5 and T8 lamp tubes may have different ballast compatibility. Ballasts are devices that regulate the electrical current to the lamp. Some LED T5 and T8 tubes are designed for direct wire installation, bypassing the need for a ballast, while others are compatible with existing ballasts. It’s important to check the compatibility requirements specified by the manufacturer.
5. Light Distribution: Due to the difference in diameter, T5 lamp tubes produce a more focused and narrower beam of light compared to T8 lamp tubes. T8 tubes have a wider beam angle, which allows for broader light distribution.
6. Application: T5 lamp tubes are commonly used in spaces that require more concentrated lighting, such as display cases, task lighting, and under-cabinet lighting. T8 lamp tubes are often used in general lighting applications for offices, commercial spaces, and industrial settings.

When considering a retrofit or replacement of fluorescent lamps with LED alternatives, it’s important to ensure compatibility with existing fixtures and ballasts (if applicable). It’s recommended to consult the manufacturer’s specifications and guidelines for the specific LED T5 or T8 lamp tubes you are considering to ensure a proper fit and optimal performance.
