You heard wrong. LED's themselves pretty much all come from China, its the mounting and implementation that varies between vendors, but the base LED/SMD has the same mean time between failures across the board. And that MTBF is a factor better than incandescent.
I use CT, PBL and Pinballbulbs intermixed on all my machines, depends on the use I need them for. For cheap spots where I know I wont have ghosting and will not directly see the bulb you can't beat .36 cent bulbs from PBL. For most frosted, CT get my business, for Warm White GI Pinballbulbs tends to be more consistent,,,, again, it all depends on what you are doing.
Worse thing, don't spend $200 on a 'kit' thats the only constant. Kits are for those who do not want to do homework and just want someone else to shop for them. Just like picking up a phone and telling someone else to buy your groceries, you will pay more and you get what you get.
