I bought what I thought was a simple headlamp option for my mother HL-23 fenix. Found the house blacked out when I visited tonight due to storms. She was sitting happily in the lounge room, reading a book, with the HL23 on high setting aka 150 lumens! Damn near blinded me when she looked up as I came in the room. I had told her a couple of times there are lower settings, she said this time she forgot and just turned it on and used it( goes to high right away). Also had to remind her to unscrew the cap to prevent parasitic drain. This is a basic go-to light option by flashaholic standards... but it clear its not family, or at least aged member friendly. So now I am hunting for lower lumen, single mode high IPX rated, non draining headlamp....how far back am I going for this one 2011, 2012, 2013?
