Plug & Play
These lamps operate off the existing fluorescent ballast and do not require any mechanical or electrical changes to the fixture. Compatible with electronic instant start ballasts.
Ballast Bypass
These lamps use the existing lamp holders to connect to the fixture being retrofitted, but do not operate off the fluorescent ballast. Rewiring of the fixture to bypass the ballast and send line voltage directly to the lamp holders is required.
