Review on BenQ 5J J2D05 011 Original Lamp by Tyrone Lee

. Gain was two 1's bulbs . As far as I can tell the bulbs are identical, the only difference being the black plastic casing on them. They have a cut out on the side that allows them to fit in the projector and the other side should have a number 1 on it. Luckily they replaced the old #2 bulb and I was able to take the old #2 bulb apart and use its plastic piece on the new bulb. After I put it back together it worked great and the price wasn't that bad.
