Apart from that, awesome tutorial, keep up the good work!
I do agree that I left out some important facts, but I can garantee that any LED that you pick, apart from those special, uber, ultra, bright, godlike LEDs, will work! :)
You don't say why, or indicate the preferred forward voltage, or the best mcd rating.
Also I note that waterclear & diffuse are two types with significant price differences, does it matter?
Good instructable, thanks.
