{"product_id":"l1515a-projector-lamp-module","title":"L1515A Projector Lamp with Module","description":"\u003cp\u003eHP's SB21 projector takes a single dedicated lamp, listed here under the code L1515A. It is the only lamp code associated with this model, so once you have confirmed SB21 is printed on your projector, there is nothing further to check before ordering.\u003c\/p\u003e\u003cp\u003eWe list a single part number, L1515A, for this lamp, with no alternative code or bare-bulb option. It is supplied as a complete module, so fitting it means removing the old housing from the SB21's lamp bay as a whole unit and replacing it with the new one.\u003c\/p\u003e\u003ch3\u003eAt a glance\u003c\/h3\u003e\u003cul\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-10772\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\u003eDoes the L1515A fit any HP projector other than the SB21?\u003c\/strong\u003e\u003cbr\u003eNo, we list this lamp specifically for the SB21.
