How to Install LED Lights in a Fluorescent Fixture

Looking to upgrade your fluorescent fixtures to LED? You might like the idea of the energy savings and long life of LED lamps—and our new lower pricing on LED tube lights makes the idea of upgrading that much more attractive—but you may be holding back out of concerns for how much trouble actually doing the upgrade will be.

No worries! We've put together a 5-minute step-by-step guide showing how simple the process is. 

Here's how to rewire a fluorescent fixture for LED tubes:

First, make sure the power's off,  then we'll open the fixture and take out the tubes.

After that, we'll remove the ballast cover:

Cut and remove all of the wires, but leave enough length on the line and neutral coming into the fixtures to connect one of your tombstones.

Remove one set of tombstones.

These tombstones are shunted; we need nonshunted.

You can use some of the leftover wire from the fixture to rewire your new tombstones.

Now you're just going to strip a small length off your line and neutral wires.

Now insert your line and neutral into one of the tombstones that has two remaining ports.

Snap your tombstones back into place.

Now you can remove the ballast. You never have to worry about one of these again.

Now remove any extra wires. You can put your ballast cover back on if you'd like to, but it's optional.

One side of the tube will be labeled AC INPUT. You're going to want to plug that into the tombstones we just wired up.

Now that your tubes are in, you're good to go.

We replaced the old prismatic diffuser with one of our new ones. It disperses the light a lot more evenly.


You can purchase just the LED tubes from ELEDLights or complete LED retrofit kits for fluorescent troffers. And if you run into any trouble with your upgrade, our team is just a phone call, text, or email away!
