{"product_id":"310-6747-projector-lamp","title":"310-6747 bare projector lamp","description":"\u003cp\u003e310-6747 is a bare 156-watt bulb built to go inside an existing Dell 3400MP or 3500MP lamp housing, rather than arriving with a housing of its own. It suits owners whose current housing is in good condition and only the bulb itself has failed or dimmed. Rated life for this bulb is 3000 hours.\u003c\/p\u003e\u003cp\u003eThe same lamp is also sold under code 725-10003, so either number will bring up this bulb. Because this is the bare version, you'll need to transfer it into your existing housing rather than fitting a new one - if your housing is cracked or the fan mount is damaged, the module version listed separately may suit you better.\u003c\/p\u003e\u003ch3\u003eAt a glance\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWattage\u003c\/strong\u003e — 156 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated life\u003c\/strong\u003e — 3,000 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-08741\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility\u003c\/strong\u003e — 2 projector models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eShould 3400MP owners pick this bare 310-6747 or its housed counterpart?\u003c\/strong\u003e\u003cbr\u003eThis is the bare bulb only, meant to be fitted into your current Dell 3400MP or 3500MP housing. A separate listing under the same part number offers the bulb already built into a new housing, for cases where the housing itself needs replacing too.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill 725-10003 fit in place of 310-6747?\u003c\/strong\u003e\u003cbr\u003eYes, both numbers describe the same 156-watt bulb for the 3400MP and 3500MP. They are alternative codes rather than different products, so either one ordered will get you this bulb.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need any tools to swap the bulb into my housing?\u003c\/strong\u003e\u003cbr\u003eMost Dell 3400MP and 3500MP housings open with a small screwdriver to release the retaining screws. Take care when lifting the old bulb out, as the housing clips can be brittle after repeated use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if it's the bulb that's failed rather than the housing?\u003c\/strong\u003e\u003cbr\u003eIf the projector reports a lamp error, fails to strike, or the image has dimmed steadily over time, the bulb itself is the more likely cause. A cracked housing or scorched socket points instead to the housing needing attention.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does a 3000-hour rating actually mean day to day?\u003c\/strong\u003e\u003cbr\u003eIt's the number of hours the lamp is expected to run before output drops enough to be worth replacing. Heavy daily use in a classroom or hall will reach that figure sooner than occasional use in a home setting.\u003c\/p\u003e","brand":"Lamps Authority","offers":[{"title":"Default Title","offer_id":48182642704620,"sku":"LA-08741","price":132.85,"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\/310-6747-projector-lamp","provider":"Lamps Authority","version":"1.0","type":"link"}
