Is it true that different sizes/shapes of reflector can significantly
influence total light output?
I have noticed in 2 lights that I have using the McR27L reflector that
the total output isn't quite as much as expected for the drive
levels of these lights, compared to lights with the same leds
and drive levels but using smaller and shallower reflectors.
Both these lights also have sapphire glass, whereas the others have
UCL lenses, but my understanding is that the difference in output from
using these 2 different windows would be almost impossible to detect,
whereas in fact its quite noticeable.
I don't know much about optics but perhaps the length and overall surface
area of the 27L results in less overall light being reflected out the window
and more light being aborbed beforehand?
