Default Home Theater Projector Replacement Lamp Question

I have a Optoma HD142x home theater projector that is in need of a new replacement lamp. This is my first time through this process - does anyone have an experience or suggestions? Should I attempt to replace the bare bulb or just go for the whole module? Found some options at this site - https://projectorquest.com/product/o...r-lamp-module/ - with an inexpensive OEM version. Does anyone have experience with this? Any other suggestions for online retailers? Does anyone have experience with the compatibles or bare bulbs?

I've got over 2,000 hours on a lamp from Projector Lamp Experts. Might give them a try.

I've been using (bare) bulb replacements as well as non-OEM lamp housings in my BenQ W1070 for years now. For the most part, it's been "fine", but there is such a wildly inconsistent level of quality to them that I'm honestly starting to reconsider the practice, especially as of today...

I've bought bulbs from a half-dozen different sources, and there's been a pretty significant variance in how bright they are. Nothing egregiously "bad" really, but several were noticeably brighter than others.

As far as life goes, again, wildly inconsistent... Most of the "cheap" ones I've bought (say $25 or so from Chinese wholesalers) have lasted a few hundred hours or so, but I've had more than one pop at a hundred hours or less.

I've also bought full (non-OEM) lamp housings from a few places at this point, and while those have pretty universally served me better (more in the 1,000-1,500 hour range), nothing has even remotely come close to the life I got out of my original OEM housing that came with the projector. That thing is noticeably dimmer now than it was at birth, but it has around 3500 hours on it, and still fires up.

When you consider that generally a bare bulb (for that PJ anyway) is $20-$40, a replacement (knockoff) housing is $100 ish, and a legit OEM one is around $200+, it still makes sense to buy the bare bulbs even if they do pop early.... as long as you can trust it's not going to damage anything.

Which brings me to today. A couple of weeks ago I replaced a bare bulb in a (non-OEM) housing I'd bought, and last night it overheated and ruined my projector. It got so hot it melted some foam insulation in the light path, and covered the lens in a bunch of dust and garbage. Even after dissembling and cleaning out the entire unit, it's taken a massive hit to PQ.

I just ordered a new PJ this morning, and I'll be seriously reconsidering my bulb purchasing habits going forward...
