Nitecore EC23 - Spot at Center of Beam

I received the new Nitecore EC23 today. The beam has a noticeable round, dark spot at the center. Attached is a photo, it is much more noticeable in person. Has anyone run into this before? Is this a defect in the light, or just the way the reflector projects the light?

A picture of the EC23 with his friends:

My XT2CR Klarus received recently, also have this. This remember my old MT1A and MT1C of Nitecore with XP-G R5 Wink , in any case, this is only noticiable for make a pic to a white wall, in normal use is not relevant (at least for me).

It’s probably due to the combination of the swallow reflector and the big surface area of the XHP35.
You could try sending an email at Nitecore to see what they have to say about it.

Does te dark spot disappear at a dstance ? If so, it means that Nitecore did a good at focusing the LED for max throw but at the price of a dark spot in close range use

The fence in my yard is at 50 yards, and you can still see the spot at that distance.

I just sent an email to Nitecore, I will see what they say.

Same issue here, but mine does not shows on longer distance or at least I did not notice...

my picture has been enhanced so it can show the spot better...mine is less presentable than the picture in person...

i asked about that exact question here.

Yeah i expected this since the spec is quite similar to Nitecore Concept One which i have and i dont like the black hole with cross in the middle also the green on the corona is also ugly but not noticeable on longer distance. Despite it’s ugly beam i quite like the Concept One fits nice in hand.

I still have my Nitecore EC23 on the way probably next week.

This is the beamshot from Nitecore Concept 1, it looks like the EC23 has bigger black hole compared to Concept 1, concept one also has green cross in the middle.

I noticed a hole in the center of the hotspot on my Acebeam H15 XHP70.2 NW version but didn’t see it in the CW version. I’m thinking of putting on some DC-Fix to diffuse it. But the flood on this thing is already insane compared to other headlamps the the Wizard and Olight H2R Nova so not sure if DC-Fix will make it overly floody.

I don't notice it outdoors. I'm told DC-fix, emitter swap to XHP35 HI, or OP reflector helps. I'm not sure it can be avoided with XHP35 HD and a SMO reflector that size.
