{"product_id":"l1550a-projector-lamp-module","title":"L1550A Projector Lamp with Module","description":"\u003cp\u003eShared between Compaq and HP badges, the L1550A lamp fits the Compaq MP1400 and MP1800 alongside the HP MP1400, MP1600 and MP1800. Rated at 120 watts for 1,000 hours, it reflects the shared manufacturing relationship between the two brands during this era of projectors.\u003c\/p\u003e\u003cp\u003eThis lamp also appears under the codes 118052-001 and L1551A, both referring to the identical part. As no photograph exists for this listing, we note its specification rather than its appearance: a complete lamp and housing module, not a bare bulb, ready to fit any of the five listed projectors.\u003c\/p\u003e\u003ch3\u003eAt a glance\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWattage\u003c\/strong\u003e — 120 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated life\u003c\/strong\u003e — 1,000 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-10774\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\u003eWhy do Compaq and HP projectors share the exact same lamp?\u003c\/strong\u003e\u003cbr\u003eCompaq and HP shared engineering resources for their earlier projector ranges before Compaq's brand was absorbed into HP. The MP1400 and MP1800 models sold under both names are the same underlying hardware, which is why L1550A fits either badge.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre 118052-001 and L1551A the same as L1550A?\u003c\/strong\u003e\u003cbr\u003eYes, we treat 118052-001, L1551A and L1550A as the same lamp and housing unit. Any of these three codes found on your old lamp or documentation matches this listing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy is there no photograph shown for this lamp?\u003c\/strong\u003e\u003cbr\u003eThis particular listing has not been photographed, so a placeholder image appears instead. The lamp supplied is still the genuine L1550A module built for the Compaq and HP MP1400-series projectors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long should the L1550A last before it needs replacing?\u003c\/strong\u003e\u003cbr\u003eIt is rated for 1,000 hours at 120 watts, a shorter figure typical of early-generation portable projector lamps. Dimming brightness or a visible flicker are practical signs to watch for as that figure approaches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the MP1600 use the same lamp as the MP1400 and MP1800?\u003c\/strong\u003e\u003cbr\u003eYes, the HP MP1600 is included among the models covered by L1550A, alongside the MP1400 and MP1800 sold under both the HP and Compaq names.\u003c\/p\u003e","brand":"Lamps Authority","offers":[{"title":"Default Title","offer_id":48182660497644,"sku":"LA-10774","price":53.04,"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\/l1550a-projector-lamp-module","provider":"Lamps Authority","version":"1.0","type":"link"}
