Honestly my Acebeam LEP is not useful for much other than being a toy. They’re impressive for sure.Is the hotspot at max range useable to the naked eye? Or do you need to view it through a scope or binoculars? Have you tried this? I'm kinda maybe thinking about buying a LEP and rigging it up between high powered binocs on a tripod. They would make amazing Morse signalling devices if two people had a set up like this. Could transmit messages probably for tens of miles.
