We went out to a freeway underpass and risked our lives in the ‘hood’ as we photographed our test lights with our camera. The location is useful since it has walls and a ceiling that can display a bike light beam pattern.  The walls have a lot of graffiti on them and actually show detail when they are lit up by a light with a wide angle. Cones and targets are set up with the far target set up at 80 yards.

It is very useful for a road cyclist or commuter to see real world useability of a light.  For a mountain biker, it’s not as good as a trail photo with a tree canopy but it does provide some insight.

These photos show the lights in the first round of our shootout.  Some other extra lights (not reviewed) are included as well.

    Great work, but might I respectfully suggest one addition to your process. Place a Lux meter down “trail/tunnel/yard” on a stand perhaps 3 feet high. Choose a distance that best represents the average focusing distance on a typical trail… 30 feet or so. When setting up each light aim it at the Lux meter so that it produces the highest reading for each light. This will insure that each light is aimed at the exact same spot. Some of the lights in your tunnel test appear to be aimed “high” (Lezyne SuperDrive XL, Lupine Betty R9) while others appear to be low (Magicshine MJ-872, Lupine Piko 3). This produces beam shots which are difficult to objectively compare. It’s just one more control which should take more than a minute per light. This would eliminate another variable. Keep up the admirable work.

    Serfas 1500 baby! That light looks great, glad to see I made a good purchase!

    I would like to see the lights in a more “real world” situation, not in a tunnel where the light cant spread as it would in an open field, or singletrack. Other than that, thanks for all the hard work.
