Do I need a ballast bypass for retrofit installations?

Feb 12th 2018

The ballast is a component in a fluorescent fixture that regulates electrical currents and provides the proper amount of energy to the fluorescent lights. LED technology does not require a ballast to regulate the amount of energy flowing to the lights. LED’s require less energy and can be sensitive to excess energy.

A ballast bypass is a common procedure to remove the ballast from the existing fixture. This is required for most retrofit installations of our dual-ended and single-ended tubes as fluorescent replacements (except for our plug-and-play tubes). A ballast bypass is a simple extra step that is a good idea for any fixture as leaving the ballast may result in buzzing, flickering, or general functionality issues.

Additionally, removing the ballast will reduce energy usage and result in even great cost-savings as ballasts continue to draw more power than necessary.

If you need more information on how to remove your ballast, please refer to our installation guides.

Here is an example ballast bypass diagram:
