I didn't like the narrow choices so I didn't vote, but I much prefer outdoor shots. What I like is much different than most though, I'll explain;
The vast majority of outdoor beamshots I see use a central focus point for the light about 100yds distant. Typically they shine down some sort of open path with trees, bushes, or other objects along the side that can be illuminated by the spill. This is fine if your goal is to have a thrower, but I prefer my beams floody. Very floody. I like to see beamshots at a much closer distance outside. Much like the white wall stuff you see, but further and of course outside. Ideally I'd like to see pictures or video that show the light in action instead of only focused on a single point.
Among the many issues with white wall photography are bounce lighting and in general a lack of distance to the target wall. I wouldn't mind closer distances IF the lights used were appropriately floody, and IF the photographer had a suitable wide angle lens. Still, I like a real life target and not a wall.
As for the typical outdoor distance stuff, it makes it difficult for me to judge a light on the criteria I find important. I end up looking at the intensity of the spill and the angle of the beam from the torch. I want to see how even the illumination is, but since the hotspot is focused far away this is almost impossible. White wall has the advantage here. Sometimes I see some shots that have a number of targets outside the main beam path and could be very useful for what I am interested in, but they fail to give relative distances along the way to the final target. This makes it impossible for me to make an accurate assessment of the spill illumination at a given distance.
My absolute ideal would be an animated gif showing the light on full power at a number of distances from a few feet maybe even up to 100yds. I'd be most interested in seeing illumination from 30-50 ft. A number of different targets would be shown. It is important to me that a wide enough lens be utilized so that the spill can be seen edge to edge even at very close distances. If the light showed a significantly different beam pattern at lower brightnesses, then you could photograph that as well. If not, well then just darken the image in your favorite program (may not be perfect, but gives you an idea). I fail to see why it's so important for some reviewers to show the lesser brightness levels with additional images rather than alternative targets. Also make sure to include any and all variables about the pictures! Not just camera exposures, but batteries utilized, reflector type, and maybe even moon phase. A pretty good example of what I like in video form is the typical review from goinggear (goingprepared) on youtube.
I do realize that there are some drawbacks to my ideal beamshots. First and foremost they would be very difficult to duplicate in a precise manner. If you were to photograph a number of lights in the same evening, that would be an easy challange. To come back and repeat the process days of weeks later would be more difficult. Outdoor targets such as trees and shrubs change over time, making comparison difficult. This can be overcome by selecting targets such as buildings, fences, vehicles etc that are not affected by time or weather in the same manner. Speaking of weather, a blanket of snow will kill any sort of accurate comparison unless the goal is to see how the light works in that particular circumstance.
I'm sure I left out a lot, but I'd say it's a good start.
