Genuine Faux Bosch parts.

I had the same thing happen buying replacement bulbs for my XBR Sony tv. They were supposed to be Sony OEM parts manufactured by Phillips. Instead I received some cheap Chinese knockoffs.
Amazon made the seller refund my purchase and pay for shipping them back. That's why I like buying on Amazon, they won't let you get burned like that. I ended getting some bulbs made in Mexico that worked great.
