Mood: Is 112 dB loud enough?? What??
I have an AIM beacon and it uses 6 LEDs arranged in a 20 mm circle. It is powered by 8 AA batteries, or a 12V DC adaptor. It also has a low and high power switch.
I would imagine you'd want an LED with the smallest possible lens angle, maybe 15 deg, to get a well focused beam. It also increases the distance it can reach.
