Why not control intensity on just one LED so it can be used as a night light inside the tent for those night jaunts to the restroom or used as a reading and/or blanket organizing light while your partner is sleeping? Or a RED LED? The LOW intensity 3 light LED output is just as bright (or brighter) then the un-adjustable full bright single LED.
