>> This might open up another can of worms....... LEDs have a specified brightness that is also spec'd with an angle of viewproduced by having a small reflector behind the active chip. Spread that energy over a wider angle and what's seen by an observer would be far less. So as a small source for reading a compass or a map, they'll do fine. As a marker or beacon, though, they may be found wanting. >> True, but one of the desired features of a personal LED marker is not being so bright as to ruin a fellow paddler's night vision, so in that application, the low luminance of an LED is an advantage. Also, one could diffuse the light and improve the angle of view somewhat by lightly sanding the LED's epoxy lens. For navigation markers on the kayak, high intensity LEDs are now available that could be treated the same way. Nonetheless, I would still wear a headlamp at night for signaling other watercraft.
