Hi,
I saw the OP late last night, and before waiting, decided to try this on an MT-G2 that was in my shorty DST (DD w/0.5ohm resistor, and 2x16340s).
I used one point of a pair of tweezers to carefully poke some holes into the dome, then I started this about 01:30 this morning, and took it out initially at about 07:30. When I took it out of the gas, there was a fairly large chunk of dome still on it, but when I just “gingerly” touched it with a small pointed stick (kind of like a longish toothpick, it popped off.
This is what it looked like at that time:
You can see the piece of the dome remnant above the star in that pic. It’s got yellowish stuff around the edges, but I think that was melted on there from when I was using the light (I think I posted somewhere about that earlier), but the main bottom part of the dome remnant was clear.
And, here’s a closer up view of the emitter with stuff still attached after that dome piece popped off:
I noticed that there seemed to be some “stuff” on one of the tiny segments, so I put it back into the gasoline for another 30 minutes. I didn’t want to leave it in there a long time, but I had an appointment, so I pulled it out. Then, when I got back, I let it soak another hour, and here’s what it looks like now:
I haven’t tested it yet, cuz I have to put it back into the light first, but anyway, how does that look? I think there’s still a bit of “stuff” on that one segment, but I don’t know if I want to either soak it more, for fear of losing the phosphors, or go poking around it, because those segments are really tiny :(. Hopefully that one piece won’t mess up the beam.
I’ll post back after I’ve had a chance to get it re-installed into the DST… hopefully it still works.
