I think some of the guys here are mixing apples and oranges...
The AB rings from Todd and Airfighter.eu are
extremely bright and a video trying to capture the glow will just burn out completely. I know there have been many
attempts of making rings out of cheap "hi-intensity" diodes, but the only thing that really counts is what you see when
you take them outside and look at it in broad daylight. Many diodes look very bright on the building table and even in
bright lamp light at home, but competing with daylight and sunshine is really tough! Not saying that it can't be done,
but there is a specific amount of light coming out of a diode at a specific voltage - and the ones that show clearly on
a bright day are - well - expensive..
