I doubt it
I would guess the lights may illuminate on moonlight because they are splitting 4.2V and the tails would get very hot, drain the battery and make it unsafe to use again
Too funny! The BLF Medusa!!! If those were sold new like that, then they could claim twice the China lumens! For example, that one on the far right has to be about 15,756 china lumen!
They actually do screw in to each other. Those are old bicycle tubes I wrapped around for some grip to use on some mounts when I use them on my handlebars. I was too lazy to take them off because they're a PITA to put back on.
