I recently purchased a multifunction headlamp. I understand the uses of the lamp and red options.
However it also has green and strobe options. What might be the use of those? Might strobe be a defense of sorts?

Emergency signal & prolonged battery life. Works for Disco Night at the shelters.

As Venchka said, emergency signal and provides better battery life.
The green output is also for night vision. http://www.equipped.org/nitevision.htm. As you can see red and green have pros and cons. I am hopelessly way behind on LED tech but when they first were coming out LEDs were most efficient putting out a single color and think Red Leds were the most efficient. In order to get white light they have to jump through a few hoops and that reduces the efficiency http://www.lrc.rpi.edu/programs/nlpi...whiteLight.asp so a single color LED may allow a slightly longer battery life.
The strobe is for rescue purposes, its far easier to pick up a flashing light at a distance. In the old days strobes were supposed to be more energy efficient. I think even with LEDs they may be as I have seen various rescue lights that have longer strobe battery life than continuous use.
If the light source is off it's not using the battery power.
Duh. [emoji106][emoji1][emoji41]
The instantaneous on and off characteristics of the LED make it perfect for intermittent (strobe) use.

I often use my headlamp walking at dusk or later. Strobe is much more noticeable to people driving cars so I often walk with strobe on vs a constant light. if I don't really need the light to see.
This. I also use the strobe feature on my headlamp when road running at night to alert drivers to my presence.Quote:

It has to do with frequency and wave length, green can be seen at a further distance.
The strobe is nice if you have friends arriving at your camp after dark.... set up a little beacon in the direction from which they will be approaching.
Done this a few times thru the years when stealth camping (all legally, of course) and it works well and is especially useful if you are some distance off-trail.
I know, not very "stealthy" lol... ;)
Approaching watercraft will think that you are on starboard tack.Quote:

Old thread, I know but..... on two occasions recently, I have been in areas where I needed to use a headlamp as a signal. On one occasion, I/we were on a hunt and without communication, no phone service and one set of batteries dead on 2-way. My friend and I were tracking a deer but needed his son to stop near where we were tracking. It was a long way back to the truck and we didn't want him to go all the way back in the snow. I set up the headlamp on strobe in a tree by the trail and it worked perfectly. he never came past us.
On another occasion, I needed to backtrack at night, off trail in an area I was unfamiliar with. I left my head lamp on strobe at the road and took a small handheld. Finding my way back was so much easier and in my estimation, saved me a ton of time.
Lots of good uses for the strobe function on today's LED headlamps.
That's what laser pointers are for.Quote:
