Welcome to BLF forum. Since you have CNC factory, I think you can start off by designing batteries tube or tube adapters or handles first.
Design some handles, tubes and adapters to use different types of tubes for batteries configuration below:
1x18650, 2x18650, 3x18650, 4x18650, 8x18650, 1x26650, 2x26650, 3x26650, 4x26650, 8x26650, 1x21700, 2x21700, 3x21700, 4x21700, 8x21700
Pick some popular flashlights like BLF GT at this moment.
But I would say shipping cost is one of the factor that you need to solve in order to sell internationally.
No problem. Just to point out to you there are many flashlight brands now. Very competitive to enter this segment. Why not offer something others are not offering. You can look at BLF GT short tube selling at USD20 price before discount.
Thanks, I just want to do some my own brands flashlight because I love flashlight , I don’t care about competitive. When I decide to do this thing, I don’t have a detail profit target.
I was hoping AWTACT can solve my puzzle(my wife’s puzzle actually) why I buy so many flashlight.
Actually every time she asked me, I told her that is because flashlight is so beautiful, only thing stop me from buying them is high price tag.
Chinese flashlights are also so great! America has really fallen behind. The quality is so much better on Chinese ones. Even brands like ZL are made in China.
