I have a reflector that i am 99% sure needs to be reamed to correct the rings in the beam. I guess i’m posting this to also confirm that, before i go tearing into a $100 light’s reflector because i’ve never done this before. I have tried permanent marker on every part of the reflector and bezel possible, and thats not changing anything. So after some examination it seems that reaming about .5 - 1mm is whats needed. check it out below.
And here how there is a lip the centering ring sits in, but that very small .5mm edge of shiny reflector is visible through the very most inner part of the centering ring?
This is the beam profile that is a result, and i have tried marker to black out anything i can, but nothing has any effect worth mentioning. I am pretty certain i need to ream?
So, if i am going to ream this reflector- do you ream from the outside of the small opening going into the reflector? Or Do you ream from the inside of the reflector going out the bottom small opening? (please see my “drawing”). thanks for the help.
I realize its annoying that some pictures are posted in the thread and some are links, my apologies. If anyone can tell me how to correct that i’d appreciate it! i tried to re post them and nothing changed.
Thank you, I was thinking that might be the best way… but I was hoping some people would corroborate that before I went at it. I have the reaming tool and almost started but figured I would post first to get some info
You will dammage the aluminum coating with a reamer because the chips coming out will curl around and touch the coating. But if you do ream it, do it from the led end and ream a little and peck it to keep chips to a minimum in the reamer so when it breaks thru it will do minimum dammage to the coating.
.
I have used a dremel tool with a carbide burr to do this. Just go slow and be careful. Use air in a can to blow chips away afterwards carefull not to let freon come out and touch the coating too, it will also dammage the coating, do not touch the coating with anthing. Any uncoated aluminum cannot come into direct view of the led or it will get very hot.
.
I’m not certian this will fix the rings, but the rim does look above the led. A centering would fix it with a rim higher than the reflector rim, but it does not look physically possible to fit one in it.
.
Good luck and check if you can get a replacement reflector, just in case things go bad.

I was definitely going to send an email to see if another reflector was an option, but I probably should do that before I touch this one. Lol. Thank you for that.
I agree if a catering ring could fit up into the reflector opening then that would be ideal, but it’s not possible unless the centering ring was on top of the emitter base I guess.
Can I used a compressor instead of can air? Low pressure I’m assuming?
Thank you for the note about not getting anything on the finished aluminum. And not touching it!
It looks like maybe it’s time for me to fet a damn Dremel… I have one but the chuck is broken so it bothers me I have to buy another one. … anyway.
What did you mean go slow and “peck” it to keep chips away? Check it maybe , mistype?
I was wondering about that, although I think this is happening because light from the emitter is catching that shiny ring of exposed reflector that sits just inside the centering ring… but so harm in trying a spacer which involves no permanent actions.
Any suggestion on what material to you? Thin sheet of plastic… something?
With the light on low, look into the light and move the beam/angle around. When a ring passes your eye you should see some part of the reflector become bright. This way you can identify exactly what part of the reflector the ring is coming from.
Wow, ok. I thought they were being sarcastic. thank you that is great advice. I’ll try it . And your right, the reflector is nicely tuned, no dark center in hotspot , etc.
OK, yea just hold it, that makes sense! thank you. and yes, i bet you may be right about the centering ring. i didnt think of that of course. its the tallest centering ring i’ve seen
Yes. And if you make a slight mistake, you’ll ruin your light. Get the LED out of focus by just a fraction of a millimeter and the nice beam is gone. Cause a few scratches or speckels on the coating and it looks like crap even when the LED is dimmly lit.
I did the moonlight check by looking in the bezel, and I’m 99% sure the original .5mm - 1mm edge j mentioned is the culprit. I’ll share some pics of that soon.
So I messaged manufacturers and one of their contacts and getting another reflector shouldn’t be a problem, it’s a sofirn / wurkkos, so… yea they are good about that stuff…
I took bezel off, put tape on mcpcb and removed centering ring. No luck removing the rings. Onto the next
So, I started reaming. Really slow, by hand, with a brand new carbide 1/2” chuck reamer with hand bar attachment. I’m not pushing down too hard abs pulling it out every couple turns to blow off reamer and reflector with compressed air.
I have nearly all of the “.5mm - 1mm” edge removed, but there is still slight rings. I believe I almost there. Had to stop for moment. But I need to remove the rest of the edge and then probably thin out the centering ring’s height.
