A fastening system and method to secure a light panel to the rear of a picture frame through the use of dual locking refittable fasteners in combination with retainers of the frame. The versatile thin illumination assembly system, consisting of the combination of the light panel and mounting system, can be applied to most existing display frames, thus converting a non-illuminated picture frame to an illuminated picture frame. The system when coupled with a frame creates an open backing that maintains the original light panel housing and eliminates heat buildup or dissipation complications often experienced with closed mounting systems. The mounting system and method requires no additional tools for the assembly process, and the resulting frame assembly is thin and easy to assemble.
