Maybe it didn’t draw my attention because I didn’t have a problem with this. My main business is retail, so I don’t face rigorous scrutiny when the goods go through customs. Some of my wholesale customers, they will ask me to stick the ce logo on the outer box.
My initial idea was to make the mode simple, and I thought that the main consumers of red light were hunters, so I didn’t directly apply the 12groups program.
The parameters provided by the official are relatively simple. Which parameters do you want to know? I can relay your questions to the technical staff of Getian.
According to the 18350 tube link, the trapezoidal threads are the “old” design, and rectangular is for the new one. So I’d think it would be rectangular.
edit: Some of the colors of 18350 tube only have trapezoidal options, so I’m guessing those host colors haven’t been updated. Looks like Red, Green, Blue, Cyan, and Silver only have trapezoidal 18350 tubes.
Nothing in particular. It’s this strange habit of collecting datasheets for every emitter I own. I used to work in hardware design over 10 years ago and although though days are long gone, I still try to obtain technical details of stuff I use or might use in some crazy future project. But it’s good to know that if any specific question comes to mind, you’re here to pass it on.
Simon, please update the titles or tags for the drivers on your AliExpress store. They are listed for specific emitters, although they are compatible (and used in listed products) for many others. There is no way to sort for “boost” or “buck” circuits unless you know both the specific size and emitter that is arbitrarily chosen to be mentioned in the product title. Some have “mA” rating, others “A”, and voltage output is not mentioned at all from the listings I’ve seen.
