{"product_id":"73p4966-projector-lamp","title":"73P4966 bare projector lamp","description":"\u003cp\u003e73P4966 is a bare projector lamp built for two IBM models, the E400 and E500. Rated at 200 watts with a 2000 hour service life, it supplies the bulb only, leaving your projector's existing housing untouched. IBM also lists this same lamp under the code 73P4954, so both numbers point to the identical part.\u003c\/p\u003e\u003cp\u003eIf your old lamp is marked 73P4954 rather than 73P4966, you are still looking at the right bulb; these are alternative codes for one lamp, not two different products. Because this is a bare lamp, you will need to move it into your current housing rather than swap a complete cage. Check your E400 or E500 housing is undamaged before ordering.\u003c\/p\u003e\u003ch3\u003eAt a glance\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWattage\u003c\/strong\u003e — 200 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated life\u003c\/strong\u003e — 2,000 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e — Bare Projector Lamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU\u003c\/strong\u003e — LA-09212\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility\u003c\/strong\u003e — 2 projector models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eIs 73P4954 the same lamp as 73P4966?\u003c\/strong\u003e\u003cbr\u003eYes. 73P4954 and 73P4966 are alternative part numbers for the same IBM lamp, so either code printed on your old bulb confirms this is the correct replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich IBM projectors take this lamp?\u003c\/strong\u003e\u003cbr\u003eThis bulb is built for the IBM E400 and E500 projectors.
