Rick,
Recently I did this. I cannot tell you that it was a terrific improvement. In my arrangement there are overhead lamps as well as the one below the deck. I am still experimenting but this probably would have worked better if the overhead lamps were dimmed a little more and the copper was not as reflective, maybe cleaning the board before drilling isn't the way to do it.
The led I used was not specified, just claimed to be super bright white, 4.5v. I am running it at about 30ma., as much as I dare.
