If the centering ring is there, maybe the o-ring is missing. Assuming the o-ring applies pressure to the lens and reflector. You might add a little heat to the bezel (hair dryer, heat gun, etc…) and see if you can loosen it.
I’m having some problems. The switch behaves strangely sometimes. It started working fine a few days ago when I loosened bezel a tiny bit. I opened it again today removed the reflector to check something and put it back and it started doing random things again. Like not not detecting clicks and sometimes detecting two. It seems to fix itself sometimes but then starts malfunctioning again.
For some reason the highest current I can get from a 30q is 3 amps. This is with a mustool MT66 with some AC mains cables instead of stock leads. With an LG MJ1 I got about 3.8 amps. The led looks brighter aswell compared to my L16. The button is slightly off center on the 30qs so could this be what’s causing the problem? I don’t even know if I’m meant to be using button tops in the first place but that is what it states on banggoods page.
Multimeters are no good for amp draws. They almost always read low, especially as the current increases they become more inaccurate. You need a clamp meter.
I’d like to ask a question I couldn’t get an answer elsewhere. I just could find one runtime graphic on google, showing that the GT mini steps down to around 10% of the output in the first 3 minutes? Can anyone confirm that? Thank you.
My GT mini has just arrived, I’m in China right now and bought directly from Lumintop. I got the neutral white version. I like it so far, waiting to get dark to test it.
I don’t know if I got lucky, but the flat on the body is perfectly aligned with the button.
