{"product_id":"bl-fp280a-projector-lamp","title":"BL-FP280A bare projector lamp","description":"\u003cp\u003eBL-FP280A is a 280-watt bare bulb rated for 2,000 hours, fitting the 3M AD50X and fifteen Optoma models spanning the DM03, DW674, EW674, EX774, OPW3200, OPW3500, OPX4000 and TX774 ranges. It replaces the bulb only, so it needs to be fitted into a housing that is already in place.\u003c\/p\u003e\u003cp\u003eThis lamp is also catalogued as 5811100173, BL-FU280A, H1Z1DSP00004, DE.5811100.173 and DE.5811100173, all naming the same bare bulb. With sixteen compatible models and closely named Optoma variants such as EW674 and EW674N, confirm your exact projector code before ordering rather than matching on the model family alone.\u003c\/p\u003e\u003ch3\u003eAt a glance\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWattage\u003c\/strong\u003e — 280 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated life\u003c\/strong\u003e — 2,000 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-07744\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility\u003c\/strong\u003e — 16 projector models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eIs EW674 the same lamp requirement as EW674N?\u003c\/strong\u003e\u003cbr\u003eYes, both the EW674 and EW674N are listed as compatible with BL-FP280A, along with the EX774 and EX774N pairing. The N suffix appears to denote a regional or specification variant rather than a different lamp.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is DE.5811100.173?\u003c\/strong\u003e\u003cbr\u003eDE.5811100.173 is an alternative code for the same BL-FP280A bare lamp, sometimes written without the periods as DE.5811100173. Both describe the identical bulb, alongside 5811100173 and BL-FU280A.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 3M AD50X really share a lamp with Optoma projectors?\u003c\/strong\u003e\u003cbr\u003eYes, our records list the 3M AD50X alongside fifteen Optoma models as compatible with BL-FP280A. Optoma has manufactured projectors sold under other brand names, which explains the shared lamp part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow hot does a 280-watt lamp run?\u003c\/strong\u003e\u003cbr\u003eWe do not publish operating temperature figures, but higher-wattage lamps generally run hotter than lower-wattage ones. Always let the projector cool for at least thirty minutes after use before opening the lamp compartment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a new housing included with BL-FP280A?\u003c\/strong\u003e\u003cbr\u003eNo, this is a bare bulb only, without a housing. Fit it into the cage already inside your Optoma or 3M AD50X projector, checking first that the existing housing and lens are undamaged.\u003c\/p\u003e","brand":"Lamps Authority","offers":[{"title":"Default Title","offer_id":48182621765868,"sku":"LA-07744","price":178.72,"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\/bl-fp280a-projector-lamp","provider":"Lamps Authority","version":"1.0","type":"link"}
