  • Patent number: 7325938
    Abstract: An indirector light fixture is described wherein the fixture is comprised of a reflector housing and a ballast housing connected together by a support arm. The reflector housing may be positioned relative to the ballast housing by movement of the support arm and maintained therein by a ratchet and pawl mechanism or other rotational restriction device. The ballast housing and ballast electronics are connected to the lamp within the reflector housing by ballast feed wires which are maintained internal of the entire fixture thereby preventing the wires from becoming entangled during installation or after installation. Additional structure is provided to further allow adjustment of the head angle relative to the ballast housing.
