How To Convert Fluorescent Tube Lights to LED

Fluorescent tube lights are the most popular lighting fixtures in the world. You’ll find them in offices, warehouses, schools, residential, commercial and industrial spaces.

In fact, if you look around your home or workplace, you’re likely to spot more CFL fluorescent tubes than incandescent bulbs any time. But, LED lights have come of age and are phasing out fluorescent. And the main reason for this change is the clear benefits that LED technology offers.

For example, LED lights have longer lifespans that range between 50,000 to 100,000 hours. They are also energy efficient, offer better light quality, are cheap to maintain.

But… converting fluorescent to LED tube lights is not always straightforward since the two technologies differ a lot. This means, you might want to know the existing infrastructure first to ensure your fluorescent tube replacements are correct and fit. In other words, LED tubes will only work if they are compatible with your existing fixtures.

How To – Convert Fluorescent to LED

In this guide, we highlight all the important things you should know when replacing your fluorescent tubes with LED tubes.

Consider the LED Tube Color Temperature

Converting Fluorescent to LED

Colour temperature is the first factor to consider when changing your overhead lighting. Color temperature measurement is in Kelvin (K) and most colors range from 2500 to 6500k. A lower Kelvin figure means the color is warm and tends to be closer to orange.

By contrast, a high Kelvin figure like 4000k means the color is cool and white in appearance. A Cool “white “color is ideal for offices and workspaces.

On the other hand, temperatures of above 5000k produce a glow resembling daylight. These colors are ideal for spaces such as a garage, high-security areas, displays, etc.

Determining Tube Sizes You Need

To find out the exact size of your bulb, check the label situated at the end of your current fluorescent tube. If you unable to find the label for whatever reason, you can use the diameter of the bulb to estimate size. The initials “T” means the bulbs come in tubular shape and the number next to the T implies the estimated diameter in inches.

For instance, the more popular and often best LED T8 tubes have a one-inch diameter (1/8). While T12 implies the diameter is 12/8 and T5 means the diameter measures 5/8 inches. All these bulbs can be used vice versa so long as they share the same bi-pin base and have the right milliamp requirements.

LED Fluorescent Replacement Tubes

Many people convert fluorescent to LED because they have a shorter lifespan, have poor light rendering and are not energy efficient. Yet, replacing the tubes is a bit more complicated because fluorescent and LED technologies are not compatible on their own.

Also, most people want to use the same fixtures due to cost and time considerations. As a result, they have no choice but to go through a costly conversion process before LED tubes can work on existing infrastructure. In a nutshell, these challenges are the reason why buyers have looked down upon LED technology in the past.

But LED technology has finally come of age when you consider the fluorescent to LED conversion choices we have today.

But, if you already have a T8 fitting in place, sometimes it’s as simple as swapping replacing the fluorescent bulbs with LED tubes. Here’s our top 3 favourite picks for you to check out on Amazon to help see if they’re suitable:
