Jimmy22: More likely they are cutting corners making the bulbs, don’t understand them and are trying to make a back door knock off one without knowing the critical issues with sourcing and mounting the components. There are some incomprehensibly dodgy suppliers in China right next door to state of the art ones. some brands will rise to the top of the market over time based on the exp of early adopters , i think Philips will be up there and anyone using Cree leds and the like with the right background ;)
I've worked at a place that was supplied what were eventually determined to be 'counterfeit' IC's through the regular buying source. (we're talking <$2 parts here). On investigation the most likely source of these was that they were rejects from the usual manufacturer/supplier that were 'dumped' to a different reseller. I doubt they wouldn't use similar practices for LED bulbs.
