I suggest you go out on your typical urban street some night and count the lights that you see in a 300' to 500' distance. Make sure to include an intersection. Even better include an intersection on a major arterial street. I would estimate the number of light sources in that distance to be well within the range of 1000 and probably more. That's a lot of competition. A light that is 1/10 of what you use out on the trail is going to be lost in the background.
