Default Is it time to change my lamp? URGENT

I have an Optoma HD67 and I've used my lamp for 1200hours. The manual says that the minimum life is 4000 hours. But as of late, I've noticed muddier blacks, less vibrant colors, changes in color depth, and banding. The overall picture is a bit duller(but not unwatchable). I haven't changed my lamp since I bought the projector two years ago. Is it time to change it or am I overreacting?

Also, is the HD66 lamp compatible with the HD67 projector?

I see different housing for the lamps. How important is this and what should I look for when I buy a new lamp? Please help me out, this is my first time.

Both of these are for my Projector but the housing looks different. Which one should I buy?

EDIT: I've come across posts where people say their bulbs exploded! what precautionary measures can I take to prevent that? I'm afraid of the new bulb being faulty as well.
Are their any other things I should look for like matching voltages?

I don't always trust the pictures on Amazon as much as the model number quoted in the description. I'd look either for the exact lamp model number recommended in your manual or find the exact model number on Optomas website and go for whatever has that in the description.

The model number of the lamp matches that in the manual. But why is the housing different?

The pictures are never accurate, and I am sure the housing will fit in your projector.

But those are knock-off replacement lamps. NOT OEM. Usually anytime they say the magic word replacement, its a knock-off and NOT OEM. The bulb itself might be OEM, meaning its from philips or what not. But the housing is NOT OEM. Thus the whole lamp assembly is suspect and definitely NOT OEM.

My suggestion is to look for an original OEM lamp from the manufacturer of your projector. Anything else, and you might be sorely disappointed, and potentially damage your projector.

Look at my experience below, with NON OEM lamp's:

Optoma has a website which sells original lamps. For the price difference, I wouldn't take a risk with any other lamp than a true OEM.

Thanks for your help. The only problem is that most sites don't ship internationally. What about this one? It's sold by Amazon.com directly(not a marketplace seller) and it says it's an OEM Optoma Lamp. There were other ones by Philips like you stated.

EDIT : I just noticed the Optoma link you posted. Checking to see if they ship internationally. Thanks for that.

EDIT #2: Unfortunately they don't ship internationally and the Asian website of Optoma doesn't as well. My nearest Optoma service center is in another city. As of now, the amazon link in this post is my last option.

Sorry for the late reply. I would try contacting the seller directly and confirm the housing is also OEM. If not, its a knock-off. By the looks of it, it appears to be another replacement version, aka knockoff. So I personally would stay away.

Have you tried to contact Optoma and ask for where you can purchase the original lamp in your region? They might be extremely helpful.

I just changed my lamp, after the replace lamp went on around 2800 hours, but my Sanyo was only rated around 2000 hours. I did read somewhere that you should periodically calibrate pjs since the bulb will dim with time well before it is supposed to be replaced. I did calibrate a couple of times before replacing, using a calibration BD, but I didn't change the settings much.

I also went with an OEM lamp. Sanyo had changed to a new lamp housing since I bought my pj, but I called and they confirmed the new replacement fit my pj perfectly, which it did.

But assuming your replace lamp light is not on yet, I wouldn't replace it.
