Are you saying that the O-ring is in one position (green?) and to move it to a different position (blue?)? It’s hard to see the lines on the interior of your drawing.
Edit: Or did you mean to move it from the blue position to the green position? FYI, I don’t have the lights yet, so can’t visualize it :).
Actually, so this brings up a question: The original place where the O-ring was had a groove, like it was meant to have an O-ring there. Since we’re removing the O-ring from the TIR lens, is the water-proofing still intact? Seems like water could enter from the front of the lens?
I’m a little confused. Are we using BOTH white o-rings. The one wrongly installed at the factory AND the one that came loose in the box? The first one going behind the lens instead of in the groove in front of the lens. And the second one going on the threads connecting the upper body to the bezel as shown in Ohaya’s picture?
I think it’s not both, but rather move the one that is on/around the TIR lens to the threaded area, but then, there’s the question I posted about what waterproofs the lens/bezel area.
Apparently when the O-ring was around the TIR lens, it was causing some rings on the beamshots.
Thanks for the measurements. Well that’s bizarre—the black version has a larger tube diameter?? Why would they bother to machine a different tube for the outer coating? Unless it was outsourced and the manufacturer allowed some variance in the boring.
I do not have the light yet, but I'm sure the o-ring does not go around the threading (photo is wrong), but goes around the underside of the tir. When the bezel is screwed on it sits on top of the head part, not around it.
Exactly. That's how I did it. This way the TIR is located slightly higher / further away from emitter, and it works! Plus the construction is still water tight, even more than the original. :)
