MTBR Light Meter Measurements:
This light measured 20 lux ont the MTBR Lux setup. In a laboratory environment with an integrating sphere, it measured at 209 actual lumens. This is excellent output for such a small light and is very close to its 250 lumen claims. It’s light output is basically on par with the more expensive Exposure Joystick which claims 325 lumens.
MTBR Actual Lumens and Lumen Hours Measurements:
Mtbr spent several days in a light laboratory facility and utilized ad $30k integrating sphere to measure some lights. The procedure is described in the video below. This is very revealing as most lights claim a certain ‘Lumen Output’ without actually measuring the actual lumen output. We are able to measure actual lumen output with this setup and the measurement for the Cateye Nano Shot is 209 lumens at the peak output.
Another excellent data point is the lumen-hour graph below. It shows exactly how the light behaves over its whole run time. A flat graph is good as it means the light output is constant over the its run and the user gets the same light outpu in hour one as in minute one of the light. It also shows how long the actual run time lasts under ‘high’ mode. The area inside the graph can be described as the total output of the light for one full battery charge.
- Very small form factor
- Excellent materials and construction
- Solid, adjustable mount
- Very good output and beam pattern
- Good value at $100
- Perfect commuter light
- Not quite enough light for trail riding.
This is a nice surprise for CatEye. Light output, form factor and price make this one of our favorite commuter lights for 2012
