An LED board rail for retrofitting an existing fluorescent light fixture includes a planar top surface configured to carry an LED board. The LED board rail includes a first flap connected to the planar top surface along a first fold line of a first side of the planar top surface, and a ...
An LED driver circuit for electrically coupling the LEDs to a power source, through the angled elbow bracket or end pieces, might also be provided within the linear light engine body. The system is configured to retrofit conventional fluorescent linear light fixtures into linear LED light fixtures...
Another style of magnetically-attachable filter systems of the present invention is a multi-magnet filter device to be used to filter light emanating from metal-rimmed light fixtures, such as recessed light fixtures, whether LEDs, incandescent, fluorescent, halogens, halides, or sodium. The light-...
