Key Differences

Type A vs. Type B

There are two main kinds of LED tubes: type a and type b. These types are not the same in how you put them in and how they work with your lights.

Type a led tubes can replace old fluorescent tubes right away. You can use them with the ballast you already have. You do not need to change any wires. Just take out the old tube and put in the new one. This is called plug-and-play. It saves time and you do not need to do electrical work. But not every ballast works with every type a tube. You should read the manufacturer’s guide before buying.

Type b led bulbs are different. You cannot use the old ballast with them. You must take out or skip the ballast and connect the tube to the main power. This makes installing harder. You might need an electrician to help. Type b led tubes connect right to the main voltage. This stops problems from the ballast and makes your lights use less energy. You also do not have to worry about the ballast breaking later.

Tip: If you want a fast and simple change, type a is best. If you want more savings and do not mind extra work, type b led bulbs are better for the future.

Quick Comparison

Here is a table to help you see the differences between type a and type b:

Type a led tubes are easy to put in. You just change the tube. Type b led bulbs need more steps, but you save more energy and have fewer problems later.

Key Points to Remember:

Type A LED Bulbs

What Is Type A

Type a led bulbs, also called plug-and-play or ballast-compatible bulbs, are designed for easy upgrades. You can use these bulbs as direct replacements for old fluorescent tubes. Type a led tubes fit into your existing fixture without the need for rewiring. You do not need to remove the ballast. This makes them a popular choice for quick lighting upgrades at home or in offices.

How Type A Works

Type a led lamps work with the ballast already in your fixture. The ballast supplies the right power for the tube. You simply insert the new bulb, and it lights up. Here is how the process works:

• The ballast sends power to the type a led tube.

• The tube uses this power to produce light.

• You do not need to change any wiring or sockets.

• The bulb depends on the ballast, so if the ballast fails, the bulb will not work.

Note: If your ballast is old or not compatible, you might see flickering or the bulb may not turn on.

Type A Installation

You can install type a led tubes with just a few steps. The process is simple and does not require special skills. Follow these steps for a safe installation:

1. Turn off the power at the circuit breaker.

2. Remove the old fluorescent tube from the fixture.

3. Check that the new type a led lamp matches your fixture and ballast.

4. Insert the new tube by lining up the pins and twisting to lock it in place.

5. Turn the power back on and test the light.

You only need basic tools like a ladder and screwdriver. You do not need to touch any wires. If you are unsure about the process, you can ask a professional for help.

Type B LED Bulbs

What Is Type B

Type b led bulbs, also known as direct wire or ballast bypass bulbs, give you a way to upgrade your lighting for better energy efficiency. These bulbs do not use the old ballast in your fixture. Instead, you connect them straight to the main power. Type b led tubes have an internal driver that lets them run on line voltage. You often see these bulbs in places where you want to cut down on maintenance and save more energy over time.

How Type B Works

Type b led lamps work by connecting directly to the power source. You must remove or bypass the old ballast. The tube gets power from the main line, not from the ballast. This setup means you do not have to worry about the ballast failing later. For wiring, you need to use non-shunted lamp holders. You also need to label the fixture to show it has been rewired for direct line voltage. This step helps keep everyone safe during future lamp changes.

Type B Installation

You need to follow special steps for type b led lamps installation. First, turn off the power at the breaker. Remove the old tube and the ballast. Next, connect the wires from the main power directly to the lamp holders. Most type b led tubes use single-end powered wiring, so you only supply power to one end of the tube. Use non-shunted sockets for safe operation. After wiring, label the fixture to warn others about the direct voltage. This installation is more complex than plug-and-play bulbs. You may want a licensed electrician to help, especially in commercial settings where voltage can be high.

⚠️ Safety Tip: Direct wiring to line voltage can be dangerous. Always follow safety rules and local codes. If you are not sure, ask a professional for help.

Type B Pros and Cons

Here are some pros and cons of type b led lamps:

Pros:

• You get higher energy efficiency because there is no ballast using extra power.

Type B LED Lamps vs. Type A

Performance

You want high performance from your lighting. Both type a and type b LED lamps offer better light quality than old fluorescent tubes. LEDs give you brighter light and better color rendering, which means colors look more natural. Lumen output tells you how bright the tube is, and Color Rendering Index (CRI) shows how true colors appear. Most LED tubes, whether type a or type b, have high CRI and good lumen output. You will notice improved light quality in your space. Type b LED lamps connect directly to power, so you do not worry about ballast problems that can lower performance over time.

Safety

Safety matters when you change your lighting. Type a tubes are safer for most people because you do not need to touch any wires. You just plug them in. Type b LED lamps need you to bypass the ballast and rewire the fixture. This step can be risky if you do not know electrical work. You must use the right sockets and label the fixture to warn others. If you wire type b LED bulbs wrong, you can create a shock hazard. Always turn off the power and ask a professional if you are not sure.

Cost

You want to save money, but you also want good lighting. Type a tubes cost less to install because you do not need an electrician. You just swap the tube. Type b LED lamps cost more at first because you pay for rewiring and sometimes new sockets. Over time, type b saves you more money. You do not need to replace ballasts, and you get better energy efficiency. Here is a quick table to compare costs:

Compatibility

You need to check if your fixture works with the tube you choose. Type a tubes need a working ballast. If the ballast fails, your light will not turn on. Type b LED lamps do not use a ballast, but you must rewire the fixture. You may need to change the sockets, especially if you switch from T8 to T12 tubes. Common issues include:

• Type b LED lamps need non-shunted sockets.

• Type a tubes may not work with all ballasts.
