For your BENQ MX843UST projector, you can choose from: lamps with housing or bare bulbs from original and generic manufacturers...

  • If you prefer an easy replacement process, buy a lamp with housing.
  • Alternatively, choose a bare bulb without housing if you already have experience with replacing bare bulbs and are willing to deal with the more challenging replacement process.
  • If you do not want to compromise on projection quality and reliability, choose an original manufacturer lamp.
  • If you prefer a cheaper option and projection quality and reliability are not your top priorities, buy a generic lamp.
  • A suitable compromise is an original bulb inside (or Diamond) lamp. It provides the quality of an original lamp, although for a better price.
