Abstract: The specification and drawings present a new light accessory holder, comprising only one part, for placing and interchanging multiple optical accessories in a lighting fixture near/in front of a light sources such as LEDs. The holder can use multiple notched springs (e.g., three) to push accessories forward and holds them in a desired position. The may be removed from the lighting fixture, so the user can load into the holder whatever accessories are needed, and then return the re-loaded holder into the light fixture. Accessories may include but are not limited to diffusers, glass components (optical filers), Hexcel Louvers, snoots, or other objects that are intended to alter the color or shape of a light source.
