My lamp just blew with 650 hours on it. I did some research on the internet and found two different bulbs. The first one matches the number on the one that blew...BQC-XVZ100001. The other one has a part number of ANK10LP/1. According to the vendor "It is a Sharp factory original replacement part". Does anyone know anything about this replacement bulb? Same lumens output? Fixes the flicker problem? Thanks, TeeTime
