It is a practical service part for keeping compatible navigation and fixture lighting operating as intended, especially when replacing a failed bulb rather than changing the whole light assembly.\u003c\/p\u003e\u003cp\u003eBecause the same bulb style is available in several voltages, the vessel’s lighting circuit voltage should be matched before installation. The bulb weighs 1 oz., which makes it easy to keep as a spare aboard for cruising, fishing, or dockside maintenance.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eClear Type T-8 incandescent bulb for compatible Perko double-contact bayonet fixtures.\u003c\/li\u003e\n\u003cli\u003e30W output with a 24 candela rating for marine lighting service.\u003c\/li\u003e\n\u003cli\u003eC-8 filament with 1-3\/8 inch L.C.L. for the correct lamp geometry in matching fixtures.\u003c\/li\u003e\n\u003cli\u003eAvailable in 12V, 24V, 32V, and 120V versions to match different vessel electrical systems.\u003c\/li\u003e\n\u003cli\u003eUseful as an onboard spare for replacing a burned-out lamp without replacing the fixture.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis Perko bulb is offered in multiple voltage configurations so it can be matched to the circuit used on the vessel or fixture.\u003c\/p\u003e\u003cp\u003eThe bulb type, 30W wattage, clear Type T-8 form, C-8 filament, 1-3\/8 inch L.C.L., 24 candela rating, and 1 oz. weight are consistent across the range.

This version suits compatible 120V AC lighting circuits and should be used only where the fixture and supply voltage match.\u003c\/li\u003e\n\u003cli\u003e0374001CLR: 12V. This version fits common 12V DC boat lighting systems used on many small and mid-size vessels.\u003c\/li\u003e\n\u003cli\u003e0374002CLR: 24V. This version matches compatible 24V DC systems often found on larger boats or vessels with higher-voltage service circuits.\u003c\/li\u003e\n\u003cli\u003e0374003CLR: 32V. This version is for compatible 32V systems, which are still found on some older or specialized marine installations.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eConfirm the fixture accepts a clear Type T-8 double-contact bayonet bulb and check the voltage stamped on the old bulb, fixture, or circuit before ordering. Using the wrong voltage can result in poor light output, premature failure, or damage to the lamp.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis bulb is a good match for boat owners and service technicians maintaining existing Perko lighting rather than converting the fixture to a different lamp style. It is especially useful to keep aboard when a vessel relies on compatible incandescent navigation or fixture lighting during evening runs, overnight anchoring, or routine maintenance.\u003c\/p\u003e","brand":"Perko","offers":[{"title":"120V","offer_id":52023136977077,"sku":"QBP505023-V6","price":75.53,"currency_code":"USD","in_stock":true},{"title":"12V","offer_id":52023137009845,"sku":"QBP505023-V4","price":75.53,"currency_code":"USD","in_stock":false},{"title":"24V","offer_id":52023137042613,"sku":"QBP505023-V2","price":75.53,"currency_code":"USD","in_stock":true},{"title":"32V","offer_id":52023137075381,"sku":"QBP505023-V9","price":75.53,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1334586_qbp505023.jpg?v=1780191770","url":"https:\/\/www.qualityboatparts.com\/products\/qbp505023","provider":"Quality Boat Parts","version":"1.0","type":"link"}
