Does anyone know how to disassemble this headlamp?

I would NOT recommend them. I have two of them, both of them work maybe 1/5 of the time. There is some kind of problem with the contacts. If you fiddle with them for a while you have a chance that it MIGHT come on. Then when its on, if you zoom in or out the modes will change or it will die again.

I cannot figure out how to disassemble this to get inside to see if there is a loose connection to re-solder. Does anyone know?

There is a circlip inside the zooming head, i've had them apart on torches/flashlights.

I'd check or re-do all solder connections,springs, switch contacts etc.

Sounds like it is possibly cracked solder at the driver or a dodgy switch contact, possibly against the body

A circlip around the Lens?

there are pictures of one disassembled either here or in the DX reviews, that'd probably help you out a lot...

It's between the moving head and tube

Exactly take the old South Berwick Basher to the one you like the least and then figure out after reconstructing the exploded one.

My first post and haven't introduced myself yet but I thought I could help here.

I mod one of these and the only way I could open the head was cutting it with a dremel. After I realiced that the lens was press fitted and after you could disassemble it.

I knew about unscerw it, but did you manage to disassembly and arrive to the led without braking anything? (not like me).

I did not have any problems with it yet ( a few months of use), but I tried to disassemble it with no luck the head is glued or something because I tried to unscrew it without luck, just to see any way to improve it with an XP-G as the con I see with it, is it should be a bit flooder than it is, I don't care loosing a bit of throw.

gorann: I'm just curious because I couldn't arrive to the led without breaking it. Actually, I did change it for an xpg R5 but without the flood to oom head, just the bare emitter.

Yavi: I could unscrew it putting some elastic bands arround the fixed part of the head, twisting them and after pull.

By the way, hi! I'm the same A380 from FL.

Thanks for the info A380 ( Y hola yo tb soy el mismo yavi :) ).

I tried to twist it quite hard, maybe mine came a bit different, because I also covered it with elasctic bands to prevent damaging it, and I could not unscrew it, maybe it was my tools were not the best, as there is little room on the fixed part of the head to catch it.

I was able to figure out what the problem with mine was. I zoomed the lens all the way out, and used pliers to unscrew the inner tube from the battery section. As mentioned above I couldn't actually get to the emitter, but all of the connections to the driver board were solid. I noticed the spring on the back of the driver was pretty short, I don't think it was even touch the battery tube. This is why zooming the light in and out, it would change modes because the spring would intermittantly touch the battery tube due to the pressure applied to it zooming in and out. So when I reassembled it, I made sure to screw the emitter tube in as far as possible with pliers. This seems to have fixed the problem with both units. I used one trouble free for about 45 minutes. During that 45 minutes I realized why the chinese didn't screw the emitter tube tightly into the battery tube. With it tightened all the way, the square projected by the emitter when zoomed is now tilted. I could care less. Apparently they were more worried about have the square level than whether or not the headlamp would work.

I'd not recommend it either - the one I have never worked from new. I hope some of the ideas here will get mine to work.

Can't say I actually care - I bought it a couple of years ago and am not sure I'd be able to find it.

I have other priorities like soldering the (tiny) microswitches back onto the car keys so they work like they ought to. Not that I can use the remotes as the assistant keeps triggering the alarm when the car is locked with the remote.
