it would be better to look at the different chinese lights as a single company.
each "brand" simply a sub family of products, if u know what i mean
think about it, how much it cost to have machinery to use and work to produce these lights, do u think small "companies" like lumapower/jetbeam/liteflux/etc. can afford to release such products? even fenix dont manufacture their own products. fenix was one of the first names to release luxeon chinese lights, and have used that name to price their products accordingly. in short, u could call them a CPFer milking machine.. hehe..)
not that its a bad thing. just that they're a single collective, each of the different brands are just names which shouldnt mean anything to the end user. see a product from any of these "companies" which u think u like, might as well get it. They arent different like for example surefire/inova/maglite are.
