10mm Radio Shack Led

[metlarules]

I bought this led from Radio Shack http://www.radioshack.com/product/index.jsp?productId=3125355&tab=summary for a project I'm working on. This thing will put a round spot of light on the wall of the garage 20ft away.Downside is it has absolutely no light outside of that spot.No spill at all just spot.
