It features a BT28 envelope shape with a clear, lensed construction and an E39 mogul base. With an initial output of 23,000 lumens, a color temperature of 4000 K (cool white), and a color rendering index (CRI) of 65, this lamp delivers high-intensity white light suited to large-area illumination. Rated life is 10,000 hours. The operating position is base-up within plus or minus 15 degrees. Licensed electricians and lighting contractors typically handle installation in commercial lighting systems. The lamp is RoHS compliant.\u003c\/p\u003e\u003cp\u003eThis lamp is rated for both indoor and outdoor commercial applications. Its 360-degree beam distribution makes it well suited to high-bay warehouses, parking structures, sports facilities, and other large open spaces where broad, uniform illumination is required. The pulse-start design supports faster restrike and improved lumen maintenance compared to probe-start metal halide sources. The lensed, open-rated construction allows use in open-style fixture housings without an additional outer envelope. Standard packaging is one lamp per pack, six per carton.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e250-watt pulse-start metal halide source with 23,000 initial lumens\u003c\/li\u003e\n\u003cli\u003eBT28 shape, clear lensed, open-rated construction for use in open fixtures\u003c\/li\u003e\n\u003cli\u003eE39 mogul base with ANSI ballast code M58\/O compatibility\u003c\/li\u003e\n\u003cli\u003e4000 K cool white color temperature with CRI of 65\u003c\/li\u003e\n\u003cli\u003e360-degree beam distribution for broad area coverage\u003c\/li\u003e\n\u003cli\u003e10,000-hour rated lamp life\u003c\/li\u003e\n\u003cli\u003eRoHS compliant\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ANSI M58\/O ballasts in open-rated commercial fixtures accepting an E39 mogul base. Verify fixture and ballast ratings before installation.

Disconnect and lock out power to the fixture before relamping. Allow the lamp to cool completely before handling, as HID lamps operate at high surface temperatures. Do not touch the outer envelope with bare hands; skin oils can cause hot spots and premature failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWattage\u003c\/strong\u003e: 250 watts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial Lumens\u003c\/strong\u003e: 23,000 lumens\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Temperature\u003c\/strong\u003e: 4000 K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Rendering Index (CRI)\u003c\/strong\u003e: 65\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Ballast Code\u003c\/strong\u003e: M58\/O\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Type\u003c\/strong\u003e: E39 Mogul\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape Designation\u003c\/strong\u003e: BT28\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLamp Type\u003c\/strong\u003e: Metal Halide, Lensed, Open Rated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStart Method\u003c\/strong\u003e: Pulse Start\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Position\u003c\/strong\u003e: Base Up, plus or minus 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBeam Spread\u003c\/strong\u003e: 360 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Clear, Cool White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Life\u003c\/strong\u003e: 10,000 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Indoor\/Outdoor, Commercial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard Package\u003c\/strong\u003e: 1 per pack, 6 per carton\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoHS Compliant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSRAM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MP250\/BU-ONLY\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSRAM","offers":[{"title":"Default Title","offer_id":51284153368882,"sku":"MP250\/BU-ONLY","price":171.42,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279747.jpg?v=1781069916","url":"https:\/\/voomisupply.com\/products\/osram-mp250-bu-only-250w-metal-halide-hid-lamp-bt28","provider":"Voomi Supply","version":"1.0","type":"link"}
