John N,
You are correct, the ARC AAA is the "perfect" red LED IMHO. I have one and I liked it so much that I bought another ARC AAA red plus 2 red Infinitys, 2 red X5Ts, 2 red Photon IIs and a red KL1. The red KL1 is way bright /ubbthreads/images/graemlins/grinser2.gif
The one I use the most out of all these is the ARC AAA red. /ubbthreads/images/graemlins/icon3.gif
