I ordered a replacement bulb for my Benq ht2150st and installed it. It malfunctioned and burned out under light usage, after about 4 weeks. They sent a replacement. It burned out in a couple weeks also. Emailed them and they said “it’s out of warranty because the first bulb you ordered is past the warranty date” what a laughable company. NEVER BUY from jaspertronics. My last OEM bulb lasted 5 YEARS!!!!! They try to get you to pay to send your projector in to clean it and do a rundown on it ☠️💀😂😂. You can thank me now or regret it later. Stay away from this joke
