In every fight, there is one alpha light

2015 Lights Shootout

Lupine Betty R10 Lens

The Lupine Betty R 14 measured much better than last year, since our test apparatus had a powerful fan directed at the light. At 4711 measured Lumens, this shows that this light is true to its claims and that it needs a lot of cooling to get maximum output. But don’t fret if you’re riding in hot nights or are not moving fast enough to give it ample cooling. This light protects itself and saves the battery by throttling down when it’s hot and it gets brighter when there’s enough airflow. We like to think of it as a speed-sensing light since it will get brighter the faster you go.

In every shootout, there has to be a top dog. This year, the Lupine Betty takes the crown by a devastating landslide. They not only spec’d a 4500 Lumen light but they also backed it up. This light is almost scary in brightness level and one really has to look away from the light head or risk seeing ‘stars’ for a moment.

The good news is the light levels are very configurable all the way to 40 Lumens without any flicker at all. This one system can serve many purposes from the longest marathon races to the fastest descent around.

The real novelty is the remote. It is so tiny, so easy to activate and so fast. It has a long range and is dependable and lightning quick. This makes it actually useable and easy to change light levels, as it will be right at your thumbs. This is particularly useful when the light is on the helmet, as one never has to take the hands off the bars.

Beam Pattern Photo

We photographed the lights in the same location setting with the same camera settings. The photos were taken in the back yard that is approximately 25 yards long. These photos feature many objects and a distinct background to analyze detail and beam pattern. Compare all Beam Patterns here »
