The body diameter is Ø92.5 mm across the range, with overall height depending on single or double stack (36 mm or 58 mm).\u003c\/p\u003e\u003cp\u003eThis series uses the FB (flat base) POM mounting system and comes precabled, which keeps the install clean on a mast, radar arch, or pole where space is limited and vibration is normal.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e3 NM visibility with a 225° white masthead sector\u003c\/li\u003e\n\u003cli\u003e10-32 VDC input for 12V and 24V DC systems\u003c\/li\u003e\n\u003cli\u003eIP68 rating; operating temperature -25°C to 55°C\u003c\/li\u003e\n\u003cli\u003eØ92.5 mm body; 36 mm single stack (2 W) or 58 mm double stack (3 W)\u003c\/li\u003e\n\u003cli\u003eApproved to COLREG72 and EN14744, with additional approvals including IEC 60945, IACS E10, USCG, ABS, M.E.D., DNV, and LR\u003c\/li\u003e\n\u003cli\u003eAnodized aluminum housing (silver or black, 25µ) with a PMMA lens and A4 stainless screws\u003c\/li\u003e\n\u003cli\u003ePrecabled with a 0.75 m shielded marine grade cable; minimum feed wire gauge 0.5 mm² (AWG 22)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis masthead light is offered in multiple configurations to match finish preference and whether you need a single or double stack body.\u003c\/p\u003e\u003cp\u003eAcross the range, the light output is white with a 225° sector, rated for 3 NM visibility, with horizontal mounting, 10-32 VDC operation, and an IP68 enclosure.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e201-011KL-FB: Finish Silver, single stack; 36 mm overall height and 2 W draw, with a two-lead cable for a single circuit.\u003c\/li\u003e\n\u003cli\u003e201-011KL-FB-B: Finish Black, single stack; 36 mm overall height and 2 W draw, with a two-lead cable for a single circuit.\u003c\/li\u003e\n\u003cli\u003e201-011KLST-FB: Finish Silver, double stack; 58 mm overall height and 3 W draw, with four leads so each light can be fed and switched separately.\u003c\/li\u003e\n\u003cli\u003e201-011KLST-FB-B: Finish Black, double stack; 58 mm overall height and 3 W draw, with four leads so each light can be fed and switched separately.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eWhat's included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eNavigation light, precabled with a 0.75 m shielded marine grade cable\u003c\/li\u003e\n\u003cli\u003eInstallation guide\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThe FB base mounts on a flat surface; the cable passes through a 7 mm center hole and the base is aligned so the arrow points forward and stays parallel with the vessel centerline. The light twists onto the base and is secured with a locking screw.\u003c\/p\u003e\u003cp\u003eIf the mounting surface is rough, adding sealant around the base helps keep water out. Keep the lens clear of obstructions so the 225° sector is not shaded by antennas, brackets, or other fittings.\u003c\/p\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003eSupply voltage is 10 to 32 VDC. For single stack lights the cable has two conductors (red positive, black negative). For double stack lights there are four conductors so each light can be powered and switched separately (Light 1: red positive and black negative; Light 2: white positive and green negative).\u003c\/p\u003e\u003cp\u003eUse a fuse or circuit breaker under 2 A (slow) and route the cable where it will not chafe or sit next to high heat sources or large electric motors.\u003c\/p\u003e\u003ch6\u003eMaterials and corrosion resistance\u003c\/h6\u003e\u003cp\u003eThe housing is anodized aluminum with a 25µ surface finish, paired with a PMMA lens and A4 stainless screws. Epoxy and polyurethane sealing materials are used to keep moisture out in a saltwater environment.\u003c\/p\u003e\u003ch6\u003eMaintenance and service life\u003c\/h6\u003e\u003cp\u003eCleaning is straightforward: wipe with a damp cloth and a mild detergent. Avoid alcohol or thinner on the lens.\u003c\/p\u003e\u003cp\u003eAn internal end-of-life signal briefly blanks the light after startup to indicate status, with longer off periods as the projected 50,000-hour lifetime is reached.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis light suits powerboats and sailboats that need a 3 NM, 225° masthead light mounted horizontally on a mast, arch, or pole. The double stack versions support installations where two separately switched masthead lights are required in the same location.\u003c\/p\u003e","brand":"Lopolight","offers":[{"title":"Silver \/ Single Stack","offer_id":52371103711413,"sku":"QBP607399-V1","price":854.63,"currency_code":"USD","in_stock":true},{"title":"Black \/ Single Stack","offer_id":52371103744181,"sku":"QBP607399-V2","price":854.63,"currency_code":"USD","in_stock":true},{"title":"Silver \/ Double Stack","offer_id":52371103776949,"sku":"QBP607399-V3","price":1253.09,"currency_code":"USD","in_stock":false},{"title":"Black \/ Double Stack","offer_id":52371103809717,"sku":"QBP607399-V4","price":1253.09,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1319297_qbp607399.webp?v=1774059698","url":"https:\/\/www.qualityboatparts.com\/products\/qbp607399","provider":"Quality Boat Parts","version":"1.0","type":"link"}
