Looking to make so 6"w x 40" long 6mm clear acrylic panels for edge lighting with LED's
the lighting will be ran along both sides of the 40" length so the light only needs to travel 3" to reach the middle of the panel
typically when you look at these they have a grid lasered on the back to catch the light
any ideas as to how far apart the grid lines should be?
are dots or any other patterns effective too?
any other tips or advice would be appreciated

Thanks!!!
