We need to add a lens on top of the LEDBorg in order to maximise the light and, effectively, shine it directly in the eyes of someone looking at it from 20m.

Has anyone had any success with any lenses? Can you recommend any?

The datasheet for the LedBorg's RGB Led is here
Which may help as it does have intensity vs displacement graphs, wavelengths and so on.
Another resource which may help is here
Hope this helps, but unfortunately beyond that, I can't really help - but hopefully another forum member may know a little more about this.
