NORMAL DISCLAIMER:
— Do NOT purchase generic brand lamps such as LTI, APO or third-party manufacturers such as OSRAM.

These lamps were NOT engineered with and for your TV…only your Philips lamp has been engineered to work flawlessly and output the best possible color. Above that, it just doesn’t make sense to choose an aftermarket lamp for a $5-$10 difference (and in many cases they are more expensive!!). Be a smart consumer and do your research! Discount-Merchant.com promises to be the low price leader in all Projection TV Lamps they carry…if this is not true, let us know and we’ll fix it!

Tools Required: Standard Philips or Flathead screwdrivers, Pair of Pliers, A new lamp.

Time Required: About 15 minutes

Abstract: This guide is being published to show how easy it is to replace your original Hitachi Lamp UX21518.

NOTE: We recommend you to use latex gloves when handling the new bulb, to avoid any dirt or oil. Our hands are naturally oily…The oil residue from our hands can cause premature failure of the lamp if the front side of the lamp is not wiped down after the installation. It doesn’t hurt to do a final wipe with a clean, non-abrasive, lint-free cloth before reinstalling your lamp…
