It also fits 3M's WX20, Dukane's Image Pro 8783 and Viewsonic's PJ3211, PJ359W and PJL3211, running at 190 watts for a 2000-hour rated life.\u003c\/p\u003e\u003cp\u003eThe identical lamp is cross-listed under 78-6969-9946-1, DT00821 and RLC-039, so check your old bulb against any of these codes if 456-8783 does not appear on it. As a bare bulb, it fits inside your existing housing rather than replacing it, so confirm your current module 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 — 190 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-07810\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility\u003c\/strong\u003e — 16 projector models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhich Hitachi models take the 456-8783 lamp?\u003c\/strong\u003e\u003cbr\u003eThe CP-X264, CP-X3, CP-X3W, CP-X5, CP-X5W, CP-X6, CP-X6W, CPX5J, HCP-600X, HCP-610X and HCP-78WX all use this lamp, alongside 3M's WX20, Dukane's Image Pro 8783 and three Viewsonic PJ models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat do DT00821 and RLC-039 refer to?\u003c\/strong\u003e\u003cbr\u003eThey are other part codes for this identical bulb, along with 78-6969-9946-1.

This listing is the bare bulb only, without a housing; it is designed to fit inside your existing lamp module, so check that your current housing and socket are still in good condition.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I reset the lamp timer once fitted?\u003c\/strong\u003e\u003cbr\u003eMost Hitachi and Viewsonic projectors include a lamp-hour reset option in the service or maintenance menu, which you should run after fitting a new bulb so the projector's usage counter starts again from zero.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen is it time to replace this lamp?\u003c\/strong\u003e\u003cbr\u003eIt is rated for 2000 hours. As your projector's built-in counter approaches that figure, or you notice the picture dimming or colours shifting, that is a sensible point to plan a replacement.\u003c\/p\u003e","brand":"Lamps Authority","offers":[{"title":"Default Title","offer_id":48182635200748,"sku":"LA-07810","price":123.68,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/5535\/8700\/files\/generic-bigbulb.png?v=1786970157","url":"https:\/\/www.lampsauthority.com\/products\/456-8783-projector-lamp","provider":"Lamps Authority","version":"1.0","type":"link"}
