The Energy Focus Intellitube® Series LED retrofit tube is our proprietary designed, all-in-one level tube that offers direct-wire (ballast not required) and direct-fit (compatible with ballasts) functions. In direct fit, it can replace an existing fluorescent lamp. In the event of a ballast failure, in direct wire mode, the Intellitube® will require re-wiring to the main power and continue to provide the most efficient light output.
