    Checking Fixture and Ballast

    You must check your fixture before you install led light tubes. The type of fixture tells you if you need a ballast. A ballast controls the flow of electricity to the tubes. Use this table to see if your fixture uses a ballast:

    Technology

    Ballast dependent?

    Incandescent

    No incandescent bulbs require a ballast.

    Halogen

    No halogen bulbs require a ballast.

    Fluorescent

    All fluorescent bulbs require a ballast.

    Compact fluorescent

    All compact fluorescent (CFL) bulbs require a ballast.

    HID

    All HID bulbs require a ballast.

    LED

    No LED bulbs require a ballast, but some are compatible with existing ballasts.

    If you see a ballast, you need to know if your new led tube lights work with it. Some led tubes are made to fit fixtures with ballasts. Others need you to remove the ballast for better led tube efficiency.

    Understanding Ballast Role

    The ballast plays a big part in how your tubes work. You need to know its role to make the right choice. Here is what you should remember:

    • The ballast decides if your led tubes will work in your fixture.

    • Some led tube lights need you to bypass the ballast. These are called direct-wire tubes.

    • If you bypass the ballast, you cannot use old fluorescent tubes in that fixture. This keeps your lighting safe.

    You should always check the types of tubes your fixture supports. This step helps you get the best efficiency and energy savings from your led lighting.
