Step-by-Step Guide to Measure LED Tubes

Measuring the Length of the Tube

Measuring an LED tube's length is simple. First, get a tape measure. Start at one end of the tube and measure to the other end. Include the pins in your measurement for accuracy. The tube's wattage often matches its length. Longer tubes usually need more wattage. When replacing a fluorescent tube, match the length and wattage to avoid problems.

If you're unsure, measure again before buying a new tube. A wrong-sized tube can cause poor performance or damage your fixture.

Determining the Diameter and Pin Type

The tube's diameter decides its type, like T5, T8, or T12. Use calipers to measure the diameter accurately. Wrap the calipers around the tube and check the size. For example, T8 tubes are 1 inch wide, while T5 tubes are thinner at 5/8 inch.

Next, look at the pin type. Check the ends of the tube to see the pin spacing. Common types are G13 for T8 and T12 or G5 for T5 tubes. Pin spacing is important for a secure fit in the fixture.

Verifying Tube Specifications for Compatibility

Before buying a replacement, check the tube's details for compatibility. First, find out the retrofit type. Here’s a quick guide:

Also, measure the tube's width to confirm its type. Check the pin spacing to match the base type. Make sure the tube works with shunted or non-shunted sockets. These steps help you pick the right LED tube for your fixture, ensuring it fits well and works great.

Understanding LED Tube Types and Compatibility

Common Tube Types (T5, T8, T12) and Their Dimensions

When picking a new LED tube, knowing T5, T8, and T12 differences helps. These types differ in size, energy use, and where they’re used. Here’s a simple comparison:

T5 tubes are small and very efficient, great for modern areas. T8 tubes are common and work well in offices or schools. T12 tubes are bigger, less efficient, and found in older fixtures. Always measure LED tubes to ensure they fit your fixture.

Ballast-Compatible vs. Ballast-Bypass Tubes

There are two main LED tube types for installation: ballast-compatible and ballast-bypass. Here’s how they compare:

• Ballast-Compatible: These work with current ballasts. They’re easy to install, like plug-and-play. However, they rely on the ballast’s condition.

• Ballast-Bypass: These need the ballast removed or bypassed. Installation takes more effort but gives better performance and less upkeep.

If you want easy setup, choose ballast-compatible tubes. For better long-term results, pick ballast-bypass tubes.

Matching LED Tubes to Fixture Requirements

To make sure the LED tube fits, match it to your fixture. Focus on these details:

Check the fixture’s size and pin type to avoid problems. Also, see if your fixture uses shunted or non-shunted sockets. This ensures the LED tube fits well and works properly.
