Inexpensive, top tier and worked well
The bulb was a top tier phillips bulb and appears to function just as bright as the original osram that came in my BenQ (from my recollection at least). It's like having a new projector. Very nice.
So much cheaper than buying the whole lamp assembly. It was tricky to install. I suggest having a magnet at the ready to hold the smallest screws. It may have been nice to have some generic instructions in the box, but I know that is hard as this bulb goes into many projectors.
