I’ve found UV lights to be very useful when traveling - checking currency, bugs, and stuff. And the Sofirn ST10 with the side emitter is a great form factor that takes both 14500 and AA. I wish they have an option to replace the red side emitter with a UV emitter. And make it out of plastic so it’s lighter. I don’t need the premium feel of metal, just want something practical for travel.
Sofirn if you’re reading this, would love that option!
