You can make this box go away Joining is quick and easy. And a bit MJe. I found no disassembly guide for this lamp, so here is one. My MJ lamp stopped reacting at some light levels. I could make it react using an external magnet, and using the external magnet actually made it Work for a while. Theory: the magnet is for some reason weakened. Change the magnet. So here is a disassembly guide: To remove the battery: 1 Get a 15mm nut.

Drill a bit into the threading using a 10mm drill. To get to the switching ring, you don't need to dismount the battery. To remove the front: You can't simply unscrew the lamp at the battery indicator. You need to remove the reflector first: Remove the glass holder ring: You need to make a Tool to unscrew this.

I did like this, and it worked fine: After removing the glass, you see the glass o-ring. You are now at the reflector. You can now un-screw the front part of the lamp, threading is in front of the battery indicator. Notice the two green O-rings.

But it needs to be clean! Now, the magnet is visible. It is a round disc, 5mm diameter and around 1mm thick.

It is very visible why it is weak. It is corroded away. This could also explain why some people complain about sand under the ring. The "sand" could be disintegrated magnet. Disassembling the Electronics: I didn't disassemble the Electronics this time, to avoid messing with the heat sink paste under the LED.

But it is straight-forward, unscrewing the two-hole ring around the LED. The magnet is easy to pick out and replace. I'll be back when I've got a replacement. I also have a Magicshine MJe.

The ring is stuck on that one. I disassembled it - that is very simple, "just" unscrew it behind the magnet ring. Writing "just", as I suspect the threading is slightly glued, it needed quite a bit of power The Square 4x7x1mm magnet was everywhere.

In general the lamps look fully like western stuff inside, especially the big MJx's. But the corrosion protection of the magnets seem to be the weak spot. Rinse the ring well!

Although I have unscrewed the front bezel and battery portion, it is unclear how to remove the lamp assembly for replacement. Magicshine has been zero help as in "no reply". Where the battery makes contact, I see a couple small holes for a deep set "special tool"? This may be the "two hole ring" mentioned above, and is near where the magnet switch is located. Any torch mechanics out there? Eventually I will need to find a source for the replacement LED.
