I think that is "fringing" due to the lens being cheap and not colour
corrected (as a camera lens is) Different wavelengths refract differently
and give a rainbow fringe.

Maybe, but it's a lot stronger than the normal chromatic aberration you
get from spectacles, I thought it was the blue LED die combined with
yellow phosphor?
