Casino Lights How Do They Light Up The Exterior Walls Of Entire Buildings Like Casino?

How do they light up the exterior walls of entire buildings like casino? - casino lights

I was just in Las Vegas and Laughlin, Nevada. MGM Grand (I think) and the Tropicana Express in Laughlin has a illiuminated outside the building. How to do it and still hide the source of light and how the light almost evenly distributed, since the building seems to have been painted by the light make it?

After all, you know where I can buy these lights to use on my homepage? Every plan you online?

Thanks
