See through the marketing and realize that with very few exceptions that new light isn't really better than the last.
I gave up on brick and mortar years ago. You will waste money. A check list of specs and a return policy.
Buying my next phone on this principle seems harder. There are more essential phone specs, and not one phone that meets them all. Thus, always dissatisfaction.
And yes, if someone makes fixed lighting that breaks the 150lpw and 80k lumen, if a flashlight reaches mid 200lpw at 10 hr 500 lumen range, I will need to upgrade. Because it ain't abour seeing, but seeing well, when safety, money, and well being is at stake.
Though I have zero hope for phone specs. My 1999 pentium 166 with 96 meg of ram on windows 98 could fly circles around a modern Android phone. Voice recognition way better. Though very little video. Uptime secret with win 98 was, mscinfig, resource meter under 23 percent, stay alive, no usb, and preventative reboot once a day. My shutdown and reboote time was 18 seconds. Today, it takes over one or two minutes on an octacore. And pages load slower than in dialup days, if you knew how to use Opera and a dialup accelerator.
