Quantity:
Walmart sells more Dorcy AAAs in a week than all Fenix production in a year. That is just 1 model. And one retailer. (They make most of the Craftsman lights sold at Sears)
Quality:
Arc, Peak, Surefire, Novatec, Elektrolumens, TnC....
Please note Fenix, LumaPower, DereeLight, JETBeam, Tiablo, Wolf Eyes, LiteFlux are medium quality low volume producers with production runs of a thousand or 2.
Favourlight has minimum order quantity of 10,000. They build 1/2 of Nuwai's lights and the Sams Club Element. But most people never heard of them because their lights are not sold under the Favourlight name.
Hint: If you cannot find at least 1 model of a manufacturer's light at a local brick and mortar store that manufacturer is not among the top 10 in terms of quantity.
Fenix-store can't compete with Walmart, let alone Walmart & Target & Lowes & Home Depot &..... Dorcy & Mag sell in all of them.
As to the top quality producers, most of us can't afford them so do not follow them much. Also they do not come out with a new model every month so there are fewer threads about them.
