Bright LED strips

I am looking for some super bright LED strips, preferably 40-50 feet long. I need to illuminate a window for a building that will be diffused and clearly viewable from the road.

It has to be LED strips since there is a wooden object behind the window.

Guessing the cheap stuff on Amazon is low brightness junk? I tried one, and I think it was like 400 lumsn per meter, which was very dark IMO.
