But it's implausible to me that, with a less bright setting at the same wavelength, and a larger sample, the results wouldn't go in the same direction.

You're assuming that any effects are due to the wavelength of the light. Unfortunately, the vastly different light intensities means that that inference cannot be drawn from this experiment. It could just as well be the light intensity that is the determining factor.
It is, of course, clearly possible that the wavelength does have a significant influence, but to claim that it's implausible for it to be anything else (e.g. light intensity, physical arrangement) is inferring too much from a rather poorly designed experiment.
