Rewiring fluorescent fixtures for LED Tubes is essential as they do not require a ballast like fluorescent tube lights. An LED tube light is produced to replace a fluorescent tube under the similar shape and measurements. In normal practice, an inductive ballast or electronic ballast is required to drive a fluorescent tube; while an LED tube does not need such kinds of ballasts. To convert to LED tubes, the ballast must be removed or bypassed by rewiring.


    • It is recommended that the following steps be completed by a qualified electrician.
    • Risk of fire. Before the replacement, the users must confirm that the LED tube light is suitable for the current fixture. Any wrong practice may cause a fire hazard.
    • Risk of electric shock. The input rating of the LED tube lights is usually between 100 and 240 Vac. Keep the power off during the replacement.

Tools needed:

    • The safety goggles
    • The safety gloves
    • The screwdrivers

Rewiring fluorescent fixtures for LED Tube instruction/information:
Installing an LED tube light in an existing fluorescent fixture is relatively simple. If the fixture has an electronic ballast, you need to remove it and then wire the power directly to the end sockets. This is fairly simple: you can use the existing wire in the fixture and marrettes (electrical wire connectors).

If you have an older fixture with a magnetic ballast and starter, you will have to remove or open the starter and remove or short the magnetic ballast.

In this example, the wires have been clipped too close to the ballast, so this ballast will not be used again.

Remember, when servicing a fluorescent fixture, electrical power to the entire fixture must be disconnected. This is not always practical in situations where a large number of fixtures are controlled from the same power control (such as in open office areas). In these cases, insulating gloves and a nonmetallic ladder should be used if the fixtures must be serviced when power is present.
