This might sound dumb to lumen/cool UI chasers but I wish I had bought a lot more lights from the 2013 era. I'd specifically like more keychain lights single mode at 25-30 lumen max, AA pocket lights around 60-80 lumens and 18650 maxing around 600-700 as the standard choices and just 1 or 2 power settings. The last few years doubled these power levels basically for everything, battery power didn't double, and number of power modes sometimes quadrupled in order to spread the gap. While you can dial down power its extra programming circuitry or clicking through modes to put up with. As an industrial user at the moment I am buying up a few fenix e05 AAA, HL23 fenix headlamps, Fenix E12 1x AA which in my opinion are great lights, (still slightly overpowered in my opinion at 85, 130,150 max) but if I don't buy them now they are going to be what double the power and modes by 2020?
