Keystone DirectDrive LED tubes eliminate the need for an external driver or ballast. For new construction installations, simply connect the 120-277-Volt line voltage directly to the sockets. For retrofit installations, bypass the existing ballast by cutting the wires and connecting the 120-277-Volt line voltage directly to the sockets. No ballast or driver is required.
