    I have recently purchased an LED Panel light and was amazed at how bright it was. But most of all the fact that you don't see the individual LED's behind the Panel, just an even distribution of light, which Leeds me to the question how is this achieved? Is there some internal diffuser or reflector. I am interested to know.

    The cover itself may be the diffuser.

    It would have to be quite a thick opaque white material like a Perspex, wonder what other material they would use as Perspex is clear and very expensive.

    The panel lights I use have a narrow circuit board wrapped around the inner circumference. Leds pointing "in". At least that's whats shown in a picture.

    It looks like the same board used, flat, in tubes.
    In tubes leds are <.5" apart and pointing down. The diffuser blends them.

    If you have super flat panels, or larger, then I have no idea.:confused:

    Free speech can be quite costly.
