Review on ABITAN 5J.J7L05.001 / 5J.J9H05.001 / 5J.JEE05.001 / 5J.J9E05.001 Projector Bare Lamp (OEM) for Benq W1070 W1080ST HT1075 HT1085ST W1070+ i700 W1500 MX662 MX720: High-quality replacement lamp for Benq projectors by Kipp Amundson

A week after the return window has expired, the lamp suddenly loses around 80% of its brightness. Less than 300 hours and now it's useless even in pitch black darkness. I have used several brands over the years and have never had this problem. They either blow or slowly fade away. What's new to me is that one of them instantly goes from normal to almost full lighting.
