The unit runs on 22 to 32 VDC and draws about 7 W (0.3 A at 24 VDC), with an IP68 seal for exposed positions on the mast.\u003c\/p\u003e\u003cp\u003eThis fixture is a good match for larger motor yachts and sailboats where redundancy matters and space for multiple masthead housings is limited.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eTwo independent white 225° masthead lights in one body, each switchable separately\u003c\/li\u003e\n\u003cli\u003eVisibility greater than 5 NM, sized for 20 m to 50 m vessels\u003c\/li\u003e\n\u003cli\u003eVertical mount format for mast or superstructure faces where the light needs to stay plumb\u003c\/li\u003e\n\u003cli\u003e22 to 32 VDC input, about 7 W total draw (0.3 A at 24 VDC)\u003c\/li\u003e\n\u003cli\u003eIP68 construction with electronics potted for resistance to water ingress and vibration\u003c\/li\u003e\n\u003cli\u003ePrecision machined 6082 aluminum housing with hard-coat anodized finish and PMMA lens\u003c\/li\u003e\n\u003cli\u003eApproved to COLREG72 and EN14744, with additional approvals including IEC 60945, USCG, and UL 1104\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -25°C to +55°C\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eMount the light on a flat, rigid surface so the lens stays vertical and the 225° sector faces forward as intended. Keep the insulating rings and isolation pieces in place when fastening to metal structures, and seal fastener penetrations to keep water out of the mounting surface and wiring path.\u003c\/p\u003e\u003cp\u003eBecause the two lights are separate, plan for two switched feeds at the helm or electrical panel and label them clearly so crews can identify primary and secondary at a glance.\u003c\/p\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003eThe light is intended for 24 VDC nominal systems and operates across 22 to 32 VDC. It is pre-wired with two screened cables using 0.5 mm2 conductors; red is positive and black is negative for each circuit. Support the wiring near the fixture so motion and vibration are not carried into the cable entry point.\u003c\/p\u003e\u003ch6\u003eCompliance and visibility\u003c\/h6\u003e\u003cp\u003eThis is a masthead light with a 225° arc and a 5 NM intensity rating, intended for installations where meeting sectoring and range requirements matters. Verify the mounting height and fore and aft placement on your vessel, especially when a second masthead light is required by length and configuration.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eRinse salt off the lens and housing during routine washdowns, and recheck fasteners and cable support after the first few trips in rough water. Avoid aggressive solvents on the PMMA lens and inspect for chafe where the leads enter the structure.\u003c\/p\u003e\u003ch6\u003eWhat’s included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eNavigation light with pre-cabled leads\u003c\/li\u003e\n\u003cli\u003eInstallation instructions\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lopolight","offers":[{"title":"Default Title","offer_id":52268961562805,"sku":"QBP515874","price":3265.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1298137_qbp515874.jpg?v=1771541072","url":"https:\/\/www.qualityboatparts.com\/products\/qbp515874","provider":"Quality Boat Parts","version":"1.0","type":"link"}
