{"product_id":"73p3191-projector-lamp","title":"73P3191 bare projector lamp","description":"\u003cp\u003e73P3191 replaces the lamp inside IBM's C400 and ThinkVision C400 projectors, a model line that IBM later transferred to Lenovo, so the identical Lenovo C400 and Lenovo ThinkVision C400 also take this bulb. It also fits the A+K AstroBeam X420 and the Microtek CX7. Rated at 250 watts and 1,500 hours, it is supplied bare, without a housing.\u003c\/p\u003e\u003cp\u003eNo alternative part numbers are currently listed for this lamp, so 73P3191 is the code to check against your projector's rating plate. Because IBM's projector business passed to Lenovo, units badged under either name use the identical part, so do not assume an IBM-branded unit needs a different lamp from a Lenovo one.\u003c\/p\u003e\u003ch3\u003eAt a glance\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWattage\u003c\/strong\u003e — 250 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated life\u003c\/strong\u003e — 1,500 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-07857\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility\u003c\/strong\u003e — 7 projector models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhy do both IBM and Lenovo projectors use this lamp?\u003c\/strong\u003e\u003cbr\u003eIBM's projector line, including the C400 and ThinkVision C400, was later sold under the Lenovo name without changing the underlying hardware, so 73P3191 fits both the IBM and Lenovo versions of this model.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes 73P3191 fit the Microtek CX7?\u003c\/strong\u003e\u003cbr\u003eYes, the Microtek CX7 is listed as compatible with this lamp, alongside the IBM, Lenovo and A+K AstroBeam X420 models that all take the identical 250-watt bulb.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre there alternative codes for 73P3191?\u003c\/strong\u003e\u003cbr\u003eNo, this lamp is currently listed under a single part number.

Dispose of the old lamp through a proper recycling point rather than general waste.\u003c\/p\u003e","brand":"Lamps Authority","offers":[{"title":"Default Title","offer_id":48182659612908,"sku":"LA-07857","price":174.13,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/5535\/8700\/files\/27082-lg.png?v=1786958888","url":"https:\/\/www.lampsauthority.com\/products\/73p3191-projector-lamp","provider":"Lamps Authority","version":"1.0","type":"link"}
