The reflector isn’t a cup, but a cup with a hole. If you make the LED hole bigger, the reflector will basically be a curved ring, and will project a ring of light, not a circle.
All my best throwers, GTmini, P30, some C8s, etc., will all have, if not a darker hole, at least a change in color (bluer light from front-firing light from spill, vs yellower from the side-firing light that hits the reflector).
The more perfect the reflector, and the larger the ratio of reflector diameter to size of the chip, the crisper and cleaner and more pronounced that hole.
Use an orangepeel reflector, and the hole goes away at some expense of throw.
It’s when a reflector is less than perfect, the chip big relative to the reflector, or it sits too high/low from optimal, that there’s no hole.
So… hole is good, no hole is not so good. By the time the beam diverges with distance, the hole goes away anyway.
I agree with Lightbringer. On my sample I did not even notice it, and is completely different from the one of the user CL33.
On bigger LEDs like the one of the MH10V2 is harder to achieve a perfect focus (a concept very open, the focus can be achieved a various desirable distances) n such a smaller reflector.
I was around at the time of the XR-E emitter and similar, where there were not so many donought holes but plenty of rings and artifacts in the beam.
At that time, the use of OP reflectors was common to mitigate the problem, and given the nature of the LED, the throw loss was not such a big deal.
Nowdays, the use of bigger and bigger LEDs (with larger emitting surface and a wider emitting angle) in smaller reflectors (diminished size and surgace, in order to fit the bigger led) forces the manufacturer to use smooth reflectors to achieve the max throw possible in this configuration.
Oh, as well as the Cd reading for the ANSI throw, but that’s for another time.
