@variablepulserate Well it depends on how you define "normal domestic" I suppose. My HK apartment (studio) has windows on 3 of the 4 walls and I'm used to having daylight 12 hours a day, including blindingly bright sun shining in around lunchtime; UK is certainly dim by comparison.
A flashlight with strobe is always in my backpack — really just in case I get stuck on an unlit bike route after sunset, but I have wondered if the strobe would ever come in handy.
