Keystone Technologies' DirectDrive HiCRI LED Tube Lamp
Keystone Technologies’ DirectDrive HiCRI LED tube lamp eliminates the need for an external driver or ballast. For new construction installations, users connect the 120–277V line voltage directly to the sockets. For retrofit installations, users bypass the existing ballast by cutting the wires and connecting the 120–277V line voltage directly to the sockets. It has a 90+ CRI, contains no mercury, is made of shatterproof glass and is designed for dry and damp locations.
