{"product_id":"et-la556-projector-lamp-module","title":"ET-LA556 projector lamp with module","description":"\u003cp\u003eUnlike most lamps in this range, the ET-LA556 serves a single projector: the Panasonic PT-L556U. It is rated at 150 watts with an 1,100-hour lamp life, and arrives as a complete module with the housing already fitted, ready to install in place of the original.\u003c\/p\u003e\u003cp\u003eThere is only one projector and one part number attached to this lamp, so compatibility checking is simple: if your unit reads PT-L556U, the ET-LA556 module is the correct fit. No alternative codes are on record for it. Because it is supplied as a module rather than a bare bulb, fitting means swapping the whole assembly rather than transferring the bulb between housings.\u003c\/p\u003e\u003ch3\u003eAt a glance\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWattage\u003c\/strong\u003e — 150 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated life\u003c\/strong\u003e — 1,100 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-09903\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility\u003c\/strong\u003e — 1 projector models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhy does this lamp only fit one projector model?\u003c\/strong\u003e\u003cbr\u003eThe PT-L556U is not part of a wider shared-chassis family in the way some Panasonic projectors are, so Panasonic issued the ET-LA556 as a dedicated lamp for this single model rather than a range.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy is the lamp-life rating 1,100 hours rather than the more common 2,000?\u003c\/strong\u003e\u003cbr\u003eThis is simply the figure Panasonic states for the ET-LA556 specifically. Rated lamp life varies between projector designs depending on how the lamp is run, so it is worth checking the figure for your exact model rather than assuming a standard number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs there a bare-bulb version of this lamp available separately?\u003c\/strong\u003e\u003cbr\u003eNot on our listings. The ET-LA556 is stocked here as a module only, with the housing included as standard, so there is nothing separate to order for this particular lamp.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre there other part numbers this lamp is known by?\u003c\/strong\u003e\u003cbr\u003eNo, ET-LA556 is the only code we have for it. There is nothing else to cross-reference when confirming compatibility, whether you are checking against an old lamp or the projector's own documentation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does the 150-watt figure tell me about this lamp?\u003c\/strong\u003e\u003cbr\u003eIt is the power rating Panasonic assigns to the ET-LA556 as fitted in the PT-L556U. This figure is fixed for this specific lamp and projector pairing.\u003c\/p\u003e","brand":"Lamps Authority","offers":[{"title":"Default Title","offer_id":48182591750380,"sku":"LA-09903","price":372.3,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/5535\/8700\/files\/generic-module.png?v=1786970169","url":"https:\/\/www.lampsauthority.com\/products\/et-la556-projector-lamp-module","provider":"Lamps Authority","version":"1.0","type":"link"}
