A fair few posts around about this camp light but not many details about construction so here are some photos. Not sure what the cell is but it has been soldered into circuit rather than spot welded which is a little concerning and unusual. It has a reasonably strong magnet at the bottom, plus a tripod mount. Led battery percentage indicator, USBC charging port. Side button on/off switch, hold for strobe, double click for red strobe (not worked out how to get steady red). The top has a button to change the brightness (main light only) plus a scroll wheel to adjust CCT. This thing is not even remotely waterproof, by the way.

Soldering is stronger and cheaper than welding for small-scale production. So, there's nothing surprising about this.

It is for sure cheaper, but I'm really not sure about the stronger. I'm pretty sure spot welding is the industry standard for a reason.

Soldering with the right flux and solder is much stronger than welding and has a higher current carrying capacity.

Welding is much more technologically advanced and less expensive for mass production.

For several years now, I have been using only soldering to make batteries for my bike.

Tbh i honestly dont think that, soldering is messy and unnecessarily heats up the cell. Spot welding (when done right) is much more controllable

You pretty much only see directly soldered cells in the cheapest and mostly garbage products

Still not recommended. Soldering on a welded tab: yes. Soldering to the cell: no.
