At 70W it draws about 3A, so it is a good match when you need the same output your fixture was built around without changing wiring, fusing, or heat load.\u003c\/p\u003e\u003cp\u003eThis is an H3 lamp with a PK22s base, so fit is defined by the bulb type and base style as much as voltage and wattage. If your light calls out H3 24V 70W on the housing, manual, or existing bulb, this is the correct format to replace it.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e24V, 70W H3 halogen bulb for marine deck lights and search lights that specify this lamp format\u003c\/li\u003e\n\u003cli\u003ePK22s base style to match H3 fixtures that use the keyed metal base\u003c\/li\u003e\n\u003cli\u003eApproximately 3A draw at 24V, helpful for confirming circuit and switch loading\u003c\/li\u003e\n\u003cli\u003eHalogen light output that stays white and focused when used with the fixture reflector and lens\u003c\/li\u003e\n\u003cli\u003eDirect replacement when the existing lamp is marked H3 24V 70W, with no changes to the light housing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eMatch three things before ordering: bulb type (H3), system voltage (24V), and wattage (70W). Swapping a 12V bulb into a 24V circuit can fail instantly, and fitting a different wattage can change beam performance and heat inside the housing.\u003c\/p\u003e\u003cp\u003eAlso confirm the base style. H3 bulbs commonly use a PK22s base and a lead connection, so check that your fixture uses the same keyed base and terminal arrangement as the bulb you are removing.\u003c\/p\u003e\u003ch6\u003eInstallation and handling\u003c\/h6\u003e\u003cp\u003eShut power off at the breaker and let the light cool before opening the housing. Halogen bulbs run hot, and a hot lens or reflector can hold heat longer than you expect in an enclosed flood or search light.\u003c\/p\u003e\u003cp\u003eHandle the bulb by the base. Avoid touching the glass with bare fingers; oils can create hot spots on the quartz envelope. Seat the base fully, secure the retainer, and make sure the lead connection is snug and routed so it cannot chafe against the reflector or pinch under the cover.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis bulb makes the most sense on boats and workboats with 24V lighting circuits where deck work lights or a search light need consistent output for docking, line handling, and spotting channel markers at night. Keeping a spare on board can cut downtime when a deck flood or search light is critical to your routine.\u003c\/p\u003e\u003ch6\u003eMaintenance and spares\u003c\/h6\u003e\u003cp\u003eAfter replacement, clean the lens and inspect gaskets so spray and washdowns do not leave salt inside the housing. If you see moisture or discoloration inside the lens, address the seal before the new bulb spends hours cooking trapped humidity.\u003c\/p\u003e","brand":"Hella Marine","offers":[{"title":"Default Title","offer_id":51551140053238,"sku":"APL564750","price":3.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0809\/6658\/2518\/files\/1280548_apl564750_jpeg.jpg?v=1787808477","url":"https:\/\/www.apollolighting.com\/products\/apl564750","provider":"Apollo Lighting","version":"1.0","type":"link"}
