It supplies the bulb sealed inside its housing, so the complete unit lifts out of the projector and the replacement seats back into the same bracket without separate handling of the bulb.\u003c\/p\u003e\u003cp\u003eThis part is also known as EST-P1-LAMP, alongside the codes 5811116635-S and 5811116635-SU for the bare-lamp options at different price points. Check whether your projector's documentation quotes any of these alternative codes, since they all describe lamps built for this same D790\/H7080HD family, though the S and SU variants omit the housing.\u003c\/p\u003e\u003ch3\u003eAt a glance\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWattage\u003c\/strong\u003e — 220 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated life\u003c\/strong\u003e — 4,000 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-10665\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility\u003c\/strong\u003e — 5 projector models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eIs EST-P1-LAMP the same part as 5811116635?\u003c\/strong\u003e\u003cbr\u003eYes. EST-P1-LAMP is an alternative code for the identical 220-watt, 4000-hour module we list as 5811116635, covering the D791ST, D792STPB, D795WT, D796WTPB and H7080HD, so either code is correct.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat's the difference between 5811116635, 5811116635-S and 5811116635-SU?\u003c\/strong\u003e\u003cbr\u003e5811116635 is the complete module with housing included. 5811116635-S and 5811116635-SU are bare-lamp variants for reusing an existing housing, priced lower, though the S and SU codes differ slightly in the exact projectors they are listed against.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the H7080HD take the same lamp as the D791ST?\u003c\/strong\u003e\u003cbr\u003eYes, Vivitek's H7080HD home-cinema projector shares the 5811116635 module with the D791ST, D792STPB, D795WT and D796WTPB business models, despite being marketed for a different setting.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does the PB suffix mean on models like D792STPB?\u003c\/strong\u003e\u003cbr\u003ePB typically denotes a bundled package variant of the base D792ST model, such as one sold with extra accessories. It does not change the lamp, and D792STPB still takes the same 5811116635 module.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I reset the lamp timer on the H7080HD after fitting 5811116635?\u003c\/strong\u003e\u003cbr\u003eOpen the H7080HD's on-screen setup menu and look for a lamp or maintenance section with a reset option, then run it once the new module is fitted, so remaining-life estimates start counting from zero again.\u003c\/p\u003e","brand":"Lamps Authority","offers":[{"title":"Default Title","offer_id":48182646735084,"sku":"LA-10665","price":121.39,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/5535\/8700\/files\/31087-xl.png?v=1786959306","url":"https:\/\/www.lampsauthority.com\/products\/5811116635-projector-lamp-module","provider":"Lamps Authority","version":"1.0","type":"link"}
