Selfbuilt's 100-Yard Outdoor Beamshot Compendium for 2011 - 51 lights, 75 pics!
Welcome to my round-up review of all my 2011 outdoor 100-yard beamshots.
 Every year, I do a number of excursions for outdoor beamshots. In this thread, I thought I would compile all my 2011 shots into one large compedium.  These are organized two ways in this thread:
Before we get started, please bear with me with some general background on how to interpret these images.  External beamshots are tricky to do well. The shots will never match what you see, due to limitations of the camera relative to your eye (e.g. lower dynamic range, limited settings, etc.). There are also numerous compensations in your brain/visual system (e.g. pupil responses, dynamic white balancing, etc.). When you throw in varying natural lighting conditions (e.g. moonshine, clouds reflecting ambient light, wind, fog, etc.), plus all the 3D topographical landscape features that can confound a single light source, you get quite a lot to deal with! I have picked a location that seems reasonably well suited to this task - a closed and deserted service road. Here is an aerial view taken from Google maps:  There is a straight line from my position (pictogram) along the road, to a copse of tree located 100 yards away. There is a dead birch tree right at the red arrow-head that is a convenient marker for the photos. I’ve also highlighted a point 30 yards from my position (blue arrow). The reason for this is shown on the side schematic for this area:  As this road goes along a ravine, and there is a significant elevation drop beginning about 30 yards in. The road makes a hard right turn as it winds down the ravine. Here is a control shot in daylight:  This shot is taken at eye level, and I have centered the camera on the dead birch tree at the center of the copse of trees at 100 yards (red arrow). The blue arrow indicates the point at 30 yards beyond which the road "falls out of view" as it dips down. I have angled the flashlights directly above the camera, focused on the center of that dead birch tree. Because of the positioning, this means that a good amount of the hotspot's corona should light up the road up to that ~30 yard mark. You will thus be able to see not only the center beam throw at 100 yards, but the corona and wider spillbeam in the foreground just in front of the camera. Note: Although you can't see them in the daylight shot, there are a series of communication towers located in a clearing ~650 yards away. The red aerial warning lights on these towers will show up as distant red dots in the background of the night time shots.  There's also a photo-reflective sign along the bottom portion of the road that you will notice in the flashlight shots.Unless otherwise indicated, all lights were run on Max, on the highest rechargeable battery option the light would take. The camera settings are optimized to show off the hotspots specifically (i.e., the pics look considerably under-exposed relative to what I subjectively saw during shooting). The pics use a 5 sec exposure, f2.7, ISO 80, automatic white balance (to minimize tint differences, which can be distracting). Images are organized first by batch, with thumbnail images that link to the high resolutions images. At the end of the thread, there is an alphabetical list sorted by maker and model, with text links to the full review and the individual batch high resolution pics. ---------------- BATCH 1 – JUNE 2011 Armytek  4Sevens   Eagletac    Fenix    Jetbeam   Lumintop    Olight    Ray Tactical  Skilhunt   Sunwayman   Tiablo   Thrunite      ---------------- BATCH 2 – AUGUST 2011 4Sevens    Eagletac  Fenix   JetBeam   Olight      Lumintop  Spark  Streamlight  Surefire   Thrunite   Zebralight  ---------------- BATCH 3 – OCTOBER 2011 4Sevens  ITP  Jetbeam    Olight   Nitecore   Surefire  Sunwayman  Thrunite     Xeno  --------------- BATCH 4 – DECEMBER 2011 Crelant  Jetbeam  Lumintop   Nitecore  Niwalker  Olight    Thrunite  Xtar  --------------- MASTER LIST OF ALL 2011 OUTDOOR BEAMSHOTS Here is a text list of all the lights, sorted alphabetically by maker and model.

A final word: As with all beamshot comparisons, simple pics can be misleading. But this should give you a rough idea of relative beam pattern and throw among these lights. Please check out the individual reviews for a lot more info on these lights.
