This LED Panel is built with the back light technology, meaning the LED chips are mounted to the backboard and it produces exceptional lighting at 130L/watt. It is lightweight, easy to install, has a long lifespan and has a even light distribution with no shadows.
The cheaper LED EDGE LIGHT Panels that have been marketed, used the PS or MS materials that are subject to the yellowing and water mark issues as early as two years after installation.
The Edge Light was a very inexpensive LED panel to produce since the LED chips were mounted on the edge, so fewer were required and light was magnified over the lens. Not the greatest design, but very cost effective for the manufacturer and retailer. We have never marketed these fixtures.
The new back light LED can be installed as a recessed, suspended and surface mount application.
