Thank You Gravelmonkey,
I see Malkoff all over the place when aficionados chime in. I looked over all their offerings, but could you please name the industry standard? I want to explore this market.
The LD40 has battery rattle but good enough to give to someone who doesn't care.
The Tikka has been replaced by ZebraLight H602 warm floody and becomes another gift to a family member. I take an ArmyTek pro Pred. Warm. for throw.
In the end, you are right the former are great lights, but I like the best performing lights I can get.
Industry standards (technical standards?) or industry leaders (manufacturers)?
Who's the "best" debates normally end up with petty arguments, there is no
overall "best" because "best" varies so much from person to person. HDS, McGizmo, Malkoff, Surefire, Peak etc are all highly rated US manufacturers. "Premium Chinese brands" such as Armytek, Foursevens, Fenix etc are hugely popular and adequate for many people's needs. If you know what sort of features you want and how much you're willing to pay, post a thread into the "recommend me a light" section with your requirements and you'll get a load of useful suggestions.
I'm not hugely knowledgeable on the standards used, ANSI FL1 is used for brightness, runtime and beam distance. It leaves a bit to be desired as it doesn't take into account any thermal or battery saving 'stepdowns' and runtime is all the way down to 10% of original brightness. Distance is to .25 lux which is barely visible, half the throw number and you'll have a more realistic 'real world use' number).
The H602w and Armytek Pro are even
nicer lights! You will eventually get into the realms of diminishing returns with price Vs quality.
