....If the Quark can do .2 lumens, the RA .3 lumen (or as low as .1, I believe) but the SF T1A goes down to 1.0 lumen, how can the T1A go "a bunch lower" than the Quark, etc? Does it go lower than the claimed spec?...
My Ra Clicky outputs 0.07 lumens on the lowest level. Assuming that's correct and using it as a reference with a lux meter, my Surefire T1A is a fraction of that -- the lux meter says 1/80th of 0.07 lumens, which would be 0.000875 lumens. With fully dark adapted eyes you can *still* navigate a small room using that, which shows how non-linear human brightness perception is.
My Photon REX's lowest level is about 1/9th the output of my Ra Clicky's lowest level, which would be about 0.0075 lumens.
My Quark 123 Mini's lowest level is about 17x brighter than the Ra Clicky's lowest level, which would be 1.21 lumens.
