Well.... I'm looking forward to trying out one of those diffused WE 6M/Cree 4 stage lights, although I've got a feeling I'll be using it on the 20% level most of the time. But dang, it's sure good to know I'll be able to spot groundhogs at 300 feet if I ever need too!
BTW, what color IS a groundhog? Seriously, I find the whole color rendition topic very interesting because I was a professional color printer for many years, and know how important the color of light is for successfully lighting a subject, and while I generally like the way most of my LED lights give a whiter appearing light, I have found that in reality they are lacking enough red to make people, in particular, look a little pale. Just my observations so far.
Of course, incandescent lights generally provide a tint in the yellow/red range, but that can be seen as a pleasing enhancement to most environments.... providing a feeling of warmth, which I think is why a lot of folks prefer them for some lighting applications.
I guess I'm most surprised that there aren't more R/G/B based LED lights out. Seems to me it would be a pretty simple thing to do. I know I've seen a few.... but I guess there just hasn't been enough interest to generate the research and development needed to produce them in quantity at this point.
By the way, I'm still not quite sure from your posts about night adapted vision whether you feel that your eyes don't become more adapted after a longer period of time (that is.... that your eyes are perfectly and completely adapted after only a few seconds), or is it that you just feel it's not necessary to be concerned with it because when you need a light, you want LOTS of light, and don't generally see the need for using lower levels under most circumstances?
