IMPORTANT NOTE: To avoid electrical shock or serious bodily harm always disable 110-277VAC power source, never cut or connect a live electrical wire. If you do not have knowledge of high voltage AC power, hire a professional electrician. Before starting this installation know that you and you alone are ultimately responsible for your safety and safety of others. If you do not feel comfortable with this project hire a professional electrician.

1.) Remove Fixture and Prep

Once you have safely removed the existing Fluorescent tube lamp fixture you can begin your ballast bypass by cutting the load and neutral wires from the ballast leaving a sufficient amount of wire to connect back to the 110 VAC power source.

2.) Cut Unneeded Wire

Cut back additional wiring on opposite side of ballast as the LED Tube lamp only requires power at one end. Remember to leave enough wire on one end in order to wire back to your original 110-277VAC Power Source.

3.) Remove Ballast from Fixture

Remove the ballast from the tube lamp housing, and save the original wiring that connected to the 110VAC. If you are planning on disposing your ballast be sure to dispose of properly within compliance of state and federal law.

4.) Strip the Power Input Wires

Strip the load and neutral wires from the first set of wires that were cut. Then group one load and one nuetral wire in order to provide power to each pin of your LED Tube Lamp.

5.) Join Wires and Connect to 110-277VAC Source

Use push-in connectors or wire nuts to connect the grouped load and neutral wires from the previous step to the load and neutral wires leading to the 110-277VAC power source. In order to avoid electrical shock be certain that your 110-277VAC power is still disabled during this process.

6.) Turn on Power and Test Connection

Connect the wires back to the 110-277VAC power source, turn power back on and enjoy your new eco friendly and energy efficient LED lights.
