The issue is that for a true professional in a trade, sometimes a ‘tool’ is just that, and longevity and performance usually take precedence. Your money will go towards something you use a lot, like a nice multimeter, or set of wrenches, or if you’re in HVAC, a non-contact thermometer, set of gauges, or power tool set that gets used a lot. When I was an electrician apprentice, we used premium tools (Greenlee, Cornwall, Klein, Milwaukie) for that reason because we can’t afford downtime for a broken tool. I break the Harbor Freight wire strippers and flush cutters all the time, but I never broke a Klein or Greenlee.
Why buy a $40 or even $30 flashlight when a $10 one from Home Depot or Lowes will do just fine? Look in the trades catalogs or tool trucks and what do you see? Snap-On/Blue Point, Cornwall/Streamlight, Maglite, sometimes you get Olight. If they get broken, even with a ‘lifetime warranty’ it’s a hassle to deal with getting a new one on warranty, so chances are it gets replaced, not fixed. My Dad was a mechanic for over 20 years and got what was on the tool trucks (Blue Point, Cornwall/Streamlight). They last a LONG time and just work, but they are expensive.
To be fair though, most don’t know about high performance flashlights beyond what they see at Home Depot, Lowes, or the hardware store. I venture in opinion they don’t go shopping on Aliexpress or Banggood. Harbor Freight is selling some halfway decent flashlights now though, but nowhere near enthusiast-grade.
