The ballast-compatible version installs directly into fixtures with electronic instant-start or rapid-start T8 ballasts, while the ballast-bypass version is designed for direct wiring to line voltage. Magnetic and T12 ballasts are not supported, so existing ballast type should always be verified before installation.
