Default Should a DLP bulb look like this

No damage taking it out of the housing, I took it out anyways cause I have to replace it non the less (2800 hours on a benq mx520). But ive never seen a hassle bent or swelled at the base. Thanks for the input

If no one answers with first hand experience, I'd suggest to just replace it and call it a day.

After looking at your photos, the bulb looks like it has overheated, these bulb's are filled with Halogen gas, if the bulb gets too hot this gas will/could cause the glass of bulb to expand.

Have you checked the ventilation on your DLP, sometime the vents can get plugged up with dust, or if there is a case fan it could have gone South for the winter and your bulb will get real hot real quick.

When you replace the bulb do not handle it with your bare hands/fingers, this will reduce the bulb life, several layers of tissue paper wrapped around the bulb with keep the oil from your hands off the bulb, (be sure to remove all paper)I have seen bulb's that have only been used for several hours explode when miss handled during install.

If a dlp is shutdown by removing power instead of using the off button, over time it will cause this. Frequent power outages will also. If not, then I'd make sure the fan is operating as well as any ventilation obstructions are clear.

Rbink now that I think about it about a week before it finally just wouldn't come on at night when I would power off the projector for some reason it would stay running, I left it alone (figured it needed to cool) but I come back an hour later and the bulb is still dimly lit and it's running, so not feeling comfortable leaving this thing on while I sleep I kicked it off by the surge protector and flipped it back on. This happened maybe 3 times, then it wouldn't fire at all, took it apart and found this. I guess I prob did this to myself but one thing I couldn't understand is why it wasn't shutting down in the first place.

If the new bulb does the same thing, you probably need to get the PJ serviced.
