Is your Mitsubishi big-screen TV getting dim or looking weird? Sounds like it might be time for a new lamp. This is a replacement projection lamp that comes WITH the plastic housing, so it's a complete unit ready to swap in. It's made to fit a bunch of Mitsubishi models like the WD-73640, WD-73740, WD-73840, WD-73C11, WD-73CA1, WD-82740, and WD-82840 (check your exact model number to be sure!). The housing is designed to fit your projector perfectly for an easy install. This is a generic replacement part (not original Mitsubishi), but it's built to do the job. You can expect a lamp life of around 2000 hours, and it comes with a 5-month warranty for peace of mind. If your TV's picture is fading or you're seeing strange colors, this lamp could be the simple fix you need to get your home theater back in action.
