Hi, most of us are just hard-core Convoy fans, no special relationship.

The info I got is simply from PM with him on Aliexpress. If you need large amount of lights, best to PM him. On this page , hover computer mouse on the arrow next to “Convoy flashlight store” (on upper left hand of page), then click on “contact now”.

He also maintains a thread here on budgetlightforum, where I assume you could PM him by clicking on his name: 【convoy】SFT40 5000K back in stock (sufficient)
