Question on "brightness"... lumens vs candelas

..but the reason flashlight reviewers favored lux is because the practice dates from the early 2000's when it was rare to get a light that came near six-digit throw (so it could be measured from any distance,) plus it was always Chinese resellers and LED manufacturers who would publish a cd number instead of lumens, which was not helpful in determining the actual output of the light; seeing a lux value meant someone had actually measured it, though that isn't as relevant now that almost no one is doing light reviews. And it's still not relevant to our hobbling OP who is under threat from people looking to attack the disabled.
Holy crap dude, do you not get it?
Candela IS lux, just calculated back to a standard distance. So that you can compare two numbers regardless of where each was measured from.
 
Celcius is literally the same thing as kelvin except you need to add or subtract 273.15 to switch between them.

Same thing here, except you need to multiply or divide by r^2 to switch between candela and lux.

That won't satisfy an attacker who isn't expecting a fully tactical 1.2 jiggalumens IN THE FACE. IF IT WAS ME, I WOULD BE LIKE
