Epson's Remarkable Lamp Guarantee
Evan Powell - Oct 20, 2010
At the bottom of our review on the Epson Home Cinema 8100 there are an unusual number of user comments expressing frustration with premature lamp failure.
...
I have spoken to Epson about this situation. They have looked into it and, like the dealers I talked to, they say they have not discovered any aberrant issues. Nevertheless, Epson wants to ensure customers that it stands behind its products. Therefore, Epson´s spokesperson has informed me that if you experience any problem with premature lamp failure on any Epson 1080p projector, you may return the lamp for a replacement lamp anytime during the life of the product´s warranty. Yes, you read that right-premature lamp failure on any Epson 1080p projector will be covered for the entire duration of the projector´s warranty, not the lamp´s warranty.
If you encounter an early lamp failure on any Epson 1080p model, Epson asks that you contact them directly at 800-637-7661 (use your PIN on PrivateLine Support Card).
In my view, this is a remarkably aggressive response on Epson´s part. To my knowledge, no other vendor offers this type of support when it comes to lamp performance. Hopefully it will put any concerns to rest on the part of those thinking of buying Epson 1080p home theater models.
