With seven compatible projectors sharing one lamp code, it is worth double-checking your exact model against the list above rather than assuming any WX3340 or X4240 variant is automatically covered.\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 — 3,500 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e — Projector Lamp with Module\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU\u003c\/strong\u003e — LA-10048\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\u003eHow many Ricoh projectors use the 308991 lamp?\u003c\/strong\u003e\u003cbr\u003eThis module is listed against seven models: the 512511, PJ WX3340, PJ WX3340N, PJ WX4240N, PJ X3340, PJ X3340N and PJ X4240N. Confirm your exact model designation before ordering, since similarly named variants can use different lamps.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does Lamp Type 9 mean?\u003c\/strong\u003e\u003cbr\u003eLamp Type 9 is an alternative name for the 308991 module used in some Ricoh manuals and menus. It describes the same part as this listing, so either reference should lead you to the correct lamp.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does one lamp fit so many different projector models?\u003c\/strong\u003e\u003cbr\u003eRicoh reuses the same lamp assembly across several projectors in a related product line where the optical engine and lamp housing are shared, which is why the 308991 module covers seven separate model numbers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a bare bulb version of the 308991 available?\u003c\/strong\u003e\u003cbr\u003eThis particular listing is the complete module with its own housing. If a bare-bulb equivalent exists for your model, it would be listed separately, so check our catalogue by your exact projector name if you want that option.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I check the lamp hours left on my projector?\u003c\/strong\u003e\u003cbr\u003eMost of these Ricoh models show remaining or used lamp hours somewhere in the on-screen setup or status menu. Refer to your projector's manual for the exact menu path, as it varies slightly between the seven compatible models.\u003c\/p\u003e","brand":"Lamps Authority","offers":[{"title":"Default Title","offer_id":48182606364908,"sku":"LA-10048","price":158.08,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/5535\/8700\/files\/24424-xl.png?v=1786957693","url":"https:\/\/www.lampsauthority.com\/products\/308991-projector-lamp-module","provider":"Lamps Authority","version":"1.0","type":"link"}
