The light output measurement is performed by placing a Lux light meter beside the light. Both are pointed at the ceiling (five feet above) of a dark room. This measurement uses the ambient light produced by the bike light. We found this to be the most effective and repeatable measure of each light.

Pointing the light directly at the meter produced varying readings depending on exactly where the light beam was centered. Also, it was highly dependent on how focused the beam pattern was. Thus we chose the ambient light measurement test as the most effective for evaluating these lights.

2008 Data:

Chart 1: Here is a graph of our measured Ambient Lux compared the lumens claims of the manufacturer. The readings are normalized using the Niterider Trinewt as the baseline since they measure their lumens output. (click to enlarge)


Chart2: Measured Lux per gram, Measured Lux per $


Chart 3: Run time vs. Weight


One of our concerns was that wider beam patterns would be inflated in our readings since they have more reflective surface (our ceiling) to bounce off from. But we found this to not be the case. Using two Dinotte 200Ls , we measured while they were pointed at the same spot, then measured with the them pointed apart for a wider beam pattern. Both cases measured in at 32 lux.

Another good indicator is the Lux measurements of two lights together was equal to the sum of each light measured separately. Example:

Dinotte 200L - 16 lux each

Dual Dinotte 200L - 32 Lux
