A few comments. Using a 30mW green laser in the US may get you rescued, but it will also get you arrested, The 5mW green laser flare from Greatlands, is amply powerful enough to safely signal someone over 30 miles away.

In tests we conducted, I could see the green laserflare reflecting off the water surface using NVG's when we were at 3000 ft altitude and about 37 miles away. That was with the laser not aimed at our aircraft. You could see the lines radiating out from the boat, pointing directly to it.

Regarding LED lights, the Surefire G2 LED was easily visible over 20 miles away as its reflector made an easily seen luminous dot.
