White vs green led light

[Buck91]

Well I'm about to swap the green led in my photon2 to a white DS, but before I do 'm trying to think of reasons to keep the green. Conditions where it would be superior or preferable. It supposedly has a longer battery life with the green led than the white, but I'm not entirely sure how/why (isn't the voltage and current regulated by battery output and resistance in these lights?).

Don't you want to get both and compare them?

From what I've heard, I think green LED's are less efficient than other colors (including white), so for the same output you would have less runtime (you should research this more, though, to make sure I'm not remembering incorrectly).

As to advantages of green over white just in terms of color, well, I'm not sure. This is something I've wondered about as well, and have done as much searching as I could handle. Basically, unlike blue or red, which have specific areas that they excel (hunting and not disturbing night vision, respectively), I haven't seen a particular use for green.

That said, our eyes are most sensitive to the yellow-green portion of the light spectrum, so chances are, at the same output level as a red or blue or whatever else light, the green will probably appear brighter. I can't say that I know of a really good use for this, but from my own experience, the green lights things up outdoors pretty well.

In the end, though, I think white will be more useful, as it gives you MUCH better color definition than green. Green, however, has a much higher gadget-factor.

If you have a green LED light, it's tough to undue something so beautiful. I'd suggest getting another white LED light instead of the swap.

Eyes are most sensitive to "warm" greenish parts of the spectrum (at least for photopic vision) and it supposedly disturbs the wildlife less (making it well suited for hunting, night time photography etc.).
