Lupine Betty R 12 – 2013 Mtbr Lights Shootout

Lights Lights Shootout

In every shootout, there has to be a top dog. The Betty R 12 is the big brother of the Betty R 9 as it includes a 2-hour battery instead of a 1.5 hour. This year, the Lupine Betty takes the crown by a devastating landslide. They not only spec’d a 3600 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.

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

And 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.

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.

2013 Claimed vs Measured Lumens


This first graph is a bar graph of each light’s Lumen output. Taller bars indicate a brighter light. The cheaper lights are on the left and the most expensive ones are on the right. And the best feature of this graph is it has the red dots on each bar that mark a light’s ‘Claimed Lumens’. This makes it very easy to compare what a light claims and what we measured its Lumen output to be.

2013 Lumen per Dollar


This next graph is our measured Lumens divided by the price of the light. Higher numbers indicate a brighter light for the money.

    costs on these things are really bad, when the cree’s started getting popular i made my own 900lm with a 7.5hr runtime that cost around 75quid.
    it had the tiny housing, custom lens, nice anodized pink housing (taken from a blt halogen) with round heatsink rear and blue anodized lean forward clamp arm (tyre shadow is an issue if bar mounted).

    some lucky thief owns it now along with my old bike, although they probably threw it away cos they didnt think to steal the charger for the custom battery.

    i have to say it again, police in Splott area, Cardiff, Wales suck bigtime, i knew who took it, gave them the address, had witnesses. they didnt care about the break in and theft, they wanted the car involved, nothing else.
    and they wonder why nobody respects them in that area.
    any other area they would have taken it seriously. sheer laziness
