UltraFire in HK, manufacturing in China
TrustFire based near the factory in China
MTE is Singapore-based, manufacturing in China

Romisen. MXDL & SAIK all appear to be the same Shenzhen company:

"MXDL" stands for "
Ming
Xing
Dong
Li"
And I think SuperFire seems to be Korean, but manufacturing in China.
And so on.
Here's what I think is going on.
All the "Fire"s seem to be branding and distribution companies, most with their own factories.
But I reckon (and this is just my surmise) that there are a bunch of small factories in the Shenzhen area, who make a run of a particular flashlight design for one of the above companies. This would mean the tooling is shared around between the factories, but the ordering companies would retain the IP.
So I think we are dealing with a bunch of independent companies based all over the Orient, all dealing with a group of small, independent factories on a contract bidding basis, but I also think a couple of firms (I cite UltraFire & TrustFire) with more permanent product lines seem to have their own factories, or at least have established long-term manufacturing contracts.
And Romisen/MXDL definitely have their own factory.
This is fascinating!
