I purchased, through Amazon, a Sony projection lamp from Discount DLP TV Lamps in May 2010. In April 2011, the lamp burned out under normal residential use. Publications suggest this lamp should last 5-8 years. Discount DLP TV Lamps refuses to respond to my inquiries. I can only conclude that they are in the business of regularly selling sub-standard - or perhaps even used - merchandise to unsuspecting on-line customers. I strongly caution any prospective buyer from being taken by this vendor and their predatory business practices.
