This is mine
Sony KDF-55E2000 Projection TV reviews - CNET Reviews
I got that message about 2 weeks ago and just got my replacement yesterday via UPS..So it lasted those two weeks and was still going. Problem is this was my 2nd bulb in that two weeks, because I thought they sent me a bad one..Appears that message is still popping up even after putting two new ones in, so There may be another problem for somewhere else..Although the picture certainly is brighter and much more crisp that message is still there.
I also bought mine here..
