Help replacing W1070 lamp?

[pedromvu]

Hi, my W1070 original lamp has already 2000 hours with low intensity mode, so I think I still got some time, but was thinking about getting a replacement lamp for when I need it.

What I was wondering is if anyone know of good places were to get this kind of items, and also asking for any suggestion (if specifically for my model better), I would prefer an official replacement instead of some third party copy of the lamp, but I also see there are different parts being sold like bare bulb vs lamp with housing, at least on amazon I am seeing a huge variation in pricing, what would be the best option? is one much more easy to install? do I need to unmount the projector to install? it was a real pain to get it filling the screen correctly

Thanks.
