How to Bypass a Ballast: Fluorescent to LED Linear Tube Lights

When making the switch from fluorescent tube lights to LED it is important to first note which type of LED tube light you need. Read our guide for how to find the right linear tube for your needs. Click to shop LED Linear Tubes.
This tutorial provides a step-by-step for bypassing a ballast when making the switch to Type B LED tube lights.

Making the Switch to LED Linear Tubes

What is a Type B LED Tube?

Type B, also known as Ballast-Bypass tubes, replace most T8 and T12 linear tubes with electronic ballasts. They require direct wiring, which means a longer installation time. Bypassing the ballast is the most efficient operation and lessens maintenance over time.


What You'll Need

Screw/nut driver
Wire connectors
Wire stripper
      tools you'll need

      Step 1: Turn off power

      Make sure the power is off at the breaker.

      Remove your old tubes.

      Use a multimeter to ensure no power is flowing to your fixture. Touch one leg of your multimeter to one socket and the other leg to the opposite socket. If it reads 0, you're good to go!

      Step 2: Cut wires

      First, remove the ballast covering. Cut all the wires connected to the ballast including the hot, neutral, and ground wires and all the wires leading from the ballast to the sockets. Be sure to cut the wires close to the ballast so you have extra wire to work with later on. Optional: Remove the ballast with your screw/nut driver.

      Step 3: Connect your wires

      Strip the wires leading to the sockets about 1 inch. Repeat on the hot and neutral wires.

      Connect one side of the fixture’s wires to the neutral wire using the connectors. Repeat on the opposite side with the hot wire.

      Step 4: Cover the wires

      Group wires neatly and place the ballast cover back on.

      Place the fixture retrofit label on the ballast cover so it is clearly visible. This will act as a reminder when replacing tubes.

      Step 5: Insert your Type B tubes

      Install your Feit Electric Type B LED linear tubes by inserting the live and neutral ends in their corresponding sockets. Check the tube’s end caps. You’ll see an N for Neutral and L for Live.
