Because 100W is a heavy load on a 12V circuit, confirm the light housing is rated for the wattage and that your wiring and switching can handle about 8.3A per lamp.\u003c\/p\u003e\u003cp\u003eThis is a straightforward service part for keeping an existing halogen light working without changing the fixture.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eH3 halogen replacement bulb for fixtures that take an H3 lamp\u003c\/li\u003e\n\u003cli\u003e12V, 100W rating for applications that call for a high-wattage H3 bulb\u003c\/li\u003e\n\u003cli\u003ePK22s base to match standard H3 sockets\u003c\/li\u003e\n\u003cli\u003eDraws about 8.3A at 12V, which helps when checking fuse and switch capacity\u003c\/li\u003e\n\u003cli\u003eUseful when you want a like-for-like replacement and do not want to retrofit the light\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eMatch the bulb type and base to your existing lamp before ordering. The simplest check is the marking on the old bulb (H3) and the base style (PK22s). If your fixture uses a retaining clip or a specific lead connection inside the housing, make sure it lines up the same way before closing the lens.\u003c\/p\u003e\u003cp\u003eThis bulb is for 12V DC systems only. It should not be used on 24V circuits.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eShut off power at the breaker or pull the fuse, then let the light cool fully before opening it. Halogen bulbs run hot, and the reflector and lens area can stay warm for a while after use.\u003c\/p\u003e\u003cp\u003eAvoid touching the glass with bare fingers. If you do, wipe it clean before powering up so skin oils do not create hot spots on the quartz.\u003c\/p\u003e\u003cp\u003eAfter reassembly, check that the gasket and lens are seated correctly so spray and washdowns stay outside the housing.\u003c\/p\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003eAt 100W, voltage drop becomes noticeable on long cable runs. Keep connections tight and corrosion-free, and size the circuit for the current draw of the lamp or lamps you are running. A quick functional check after install is steady brightness and no excessive heat at terminals or connectors.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis bulb is a good match for boats that already have an H3 halogen deck flood or spotlight installed and want a direct service replacement. It is commonly used for dockside lighting, cockpit work, deck loading, and short-duration spotlighting where the existing fixture is already set up for an H3 lamp.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eHalogen bulbs do not like moisture inside the housing. If you see condensation, address the seal or venting so the bulb is not stressed by repeated heat and cool cycles. Keeping the lens clean also helps the fixture run cooler for the same usable light.\u003c\/p\u003e","brand":"Hella Marine","offers":[{"title":"Default Title","offer_id":52269026476213,"sku":"QBP486856","price":4.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1298452_qbp486856.jpg?v=1771541500","url":"https:\/\/www.qualityboatparts.com\/products\/qbp486856","provider":"Quality Boat Parts","version":"1.0","type":"link"}
