What is T8 LED Tube?5 Things You Need to Know

The T8 LED tube is a new type of LED lighting that is becoming increasingly popular for commercial and residential applications. Unlike traditional fluorescent bulbs, T8 LED tubes use less energy and last much longer. In addition, T8 LED tubes emit very little heat, making them a safer and more efficient option for lighting.

One of the most significant advantages of T8 LED tubes is that they can significantly reduce energy bills. You could save hundreds of dollars on your energy bill each year by switching to T8 LED tubes.

T8 LED Tubes Lamp Types

There are two types of T8 LED lamps: ballast-compatible and ballast-bypass. Ballast-compatible, also known as plug-and-play lamps, can directly replace your existing fluorescent bulbs. In contrast, ballast-bypass lamps, also known as direct-wire lamps, do not require a ballast. Ballast-compatible T8 LED lamps are the most popular type and are the easiest to install. Ballast-bypass T8 LED lamps are a bit more complicated to install. Still, they are more energy-efficient since they don't require a ballast.

There are also hybrid T8 LED lamps, which are a combination of ballast-compatible and ballast-bypass lamps. Hybrid T8 LED lamps can be plugged into ballast for the first time. After the expiration of the ballast, the fixture can be rewired to bypass it.

Here is the classification of different T8 LED Tubes used by manufacturers:

- Type A: The most common type of T8 LED tube, Type A tubes are compatible with most ballasts. They are available in various lengths and wattages, and they're the most popular option for both commercial and residential applications.

-Type B: Ballast-bypass tubes are designed to provide a direct connection between the lamp and the power supply, bypassing the ballast. This results in a more efficient lighting system operation, as there is no need to waste energy in converting AC to DC and then back to AC again.

-Type A/B: Tubes are compatible with nearly all types of ballasts on the market. They also have a bypass feature, meaning it can be used without a ballast if desired.

-Type C: Is a newer tube type that is compatible with an external LED driver. With an external LED driver, you can easily control the dimming of your lights without any worries about compatibility issues. Make sure that the driver is compatible with the tubes you purchased.

The Size of The Lamp

T8 LED tubes are available in sizes ranging from 2 feet to 8 feet. The most popular size is the 4-foot T8 LED tube, which is the standard size for fluorescent bulbs.

The Shape of The Tube

T8 LED tubes also come in a variety of shapes, including circular, U-shaped, and linear. The most popular shape is the linear T8 LED tube.

Replacing Fluorescent Light Bulbs with LEDs

If you're looking to replace your fluorescent light bulbs with LEDs, there are a few things you need to know.

First, not all LEDs are created equal. There are two main types of LEDs: white and colored. White LEDs are the most common type and are typically used for general lighting purposes. Colored LEDs are less common and are typically used for specific applications, such as accent lighting.

Second, when choosing an LED replacement for a fluorescent bulb, it is essential to find an LED with a similar lumen output. It will help you to get the same amount of light from your LED as you did from your fluorescent bulb while using less energy.

Another factor to consider when replacing fluorescent bulbs with LEDs is the bulb's color temperature. Color temperature is measured in Kelvin (K), and it refers to the hue of the light emitted by a bulb. The color temperature of warm white light is approximately 3000K, while cool white light has a color temperature of 4000K or more.

When choosing an LED bulb to replace a fluorescent bulb, it is crucial to consider both the lumen output and the color temperature. Doing so will help ensure you choose an energy-efficient bulb that emits the type of light you desire.

If you want to replace your old fluorescent T8 light bulbs with LEDs, you should know a few things. First, you'll need to find LED bulbs that are compatible with your existing ballast. You can also choose to bypass the ballast altogether, but that will require some additional wiring. Either way, the process is relatively simple and can be done in a few minutes.

The process of replacement

To replace your fluorescent T8 bulbs with LED bulbs, you'll need:

- LED bulbs that are compatible with your existing ballast

- A screwdriver

- Wire cutters (if bypassing the ballast)

1. Start by turning off the power to your fluorescent fixture.

2. Remove the old bulbs from the sockets and dispose of them properly.

3. Install the new LED bulbs into the sockets. If you're using ballast-compatible bulbs, no further wiring is necessary.

4. If you're bypassing the ballast, you'll need to cut the wires leading to it and connect them directly to the LED bulbs. Consult a wiring diagram for your specific fixture to ensure you make the correct connections.

5. Once all the bulbs are installed and wired, turn on the power to the fixture and enjoy your new LED lights!


How much energy does a T8 LED tube use?

T8 LED tubes use about 10-15% of the energy of a traditional fluorescent tube.

What is the lifespan of a T8 LED tube?

T8 LED tubes can last up to 50,000 hours, which is around 25 times longer than traditional fluorescent bulbs.

What is the most popular size for a T8 LED tube?

The most popular size is the 4-foot T8 LED tube.

What types of LEDs are most common?

The most common type of LED is the white LED.

Do T8 LED Bulbs Need Ballasts?

Ballast-compatible T8 LED lamps can directly replace your existing fluorescent bulbs. In contrast, ballast-bypass lamps, also known as direct-wire lamps, do not require a ballast. Ballast-compatible T8 LED lamps are the most popular type and are the easiest to install.


T8 LED tubes are more energy-efficient and have a longer lifespan than traditional bulbs. Plus, T8 LED tubes are also much safer than traditional fluorescent bulbs. Fluorescent bulbs emit UV rays that can harm your health, whereas T8 LED tubes do not. This makes them a safer option for both you and your family. If you're looking for a more efficient and safer option for lighting, then T8 LED tubes are a great choice. They can save you money on your energy bills and last much longer than traditional bulbs. Plus, they're much safer for you and your family.
