Not shaving related, unless I need to shave in the dark during a power outage, but new for me is this BLF Q8 super-highpower flashlight, obtained through a group buy on a flashlight forum. Its output is 5,000+ lumens, with a peak intensity of 50,000+ cd, and a range of 450+ meters. It is waterproof and weighs 400g without the batteries.
