{"product_id":"379755220-projector-lamp-module","title":"379755220 projector lamp with module","description":"\u003cp\u003eNine different Vivitek models share this lamp module, from the home cinema HD2100 and HD2100U through to the RP51HD41A and RP56HD22A installation projectors. Whichever of the nine you own, the same 379755220 module fits, complete with its own housing rather than a bare bulb alone.\u003c\/p\u003e\u003cp\u003eThis lamp is also sold under two further codes, 3797048800 and 3797631900-S, so if your old bulb carries either of those numbers rather than 379755220, it is still the correct match. All three refer to the same physical lamp module.\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-10712\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility\u003c\/strong\u003e — 9 projector models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhy does my old lamp show a different part number to 379755220?\u003c\/strong\u003e\u003cbr\u003eThis lamp has been supplied under three codes over time: 379755220, 3797048800 and 3797631900-S. If your old bulb carries either of the other two, it is still the same lamp and this listing is correct.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes one lamp module really cover both the HD2100 and the RP56HD22A?\u003c\/strong\u003e\u003cbr\u003eYes. Despite the different model names, the HD2100, HD2100U, HDT2100, DVR5612 and the RP51HD41A, RP56HD21, RP56HD21A, RP56HD22 and RP56HD22A all take the 379755220 module, so a single listing covers all nine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 379755220 delivered as a housed assembly or loose glass?\u003c\/strong\u003e\u003cbr\u003eIt is a full module, meaning the bulb comes fitted inside its own housing and cage. You remove the old assembly as one piece and fit this one in its place.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I find the part number on my current lamp?\u003c\/strong\u003e\u003cbr\u003eIt is usually printed on a label on the housing itself, visible once you slide the old module out of the projector. Compare it against 379755220, 3797048800 or 3797631900-S to confirm this listing matches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is meant by RP56HD21 versus RP56HD21A in the compatibility list?\u003c\/strong\u003e\u003cbr\u003eThese are separate model variants that Vivitek sold under closely related names.
