Operating on 10-30VDC, it delivers 270 lumens of warm white illumination while consuming 3.0W, making it a suitable replacement for conventional 20W halogen bulbs in compatible fixtures.\u003c\/p\u003e\u003cp\u003eIts circular circuit board incorporates 21 high-output surface-mounted LEDs arranged to distribute light across a 120-degree beam. The wide board design accommodates a greater number of LEDs within the fixture, while an integrated PWM constant-current driver maintains controlled electrical operation across the supported voltage range.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003eG4\/GU4 back-pin connection for compatible vertical-mounted sockets.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e10-30VDC input supports common 12V and 24V DC marine electrical systems.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e270-lumen warm white output from 21 high-output SMD LEDs.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e3.0W power consumption with 20W halogen equivalency.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e120-degree beam angle for broad directional illumination.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e1.37-inch (34.8 mm) diameter circular LED board.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eIntegrated PWM constant-current driver with over-voltage protection.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and installation\u003c\/h6\u003e\u003cp\u003eThe back-pin configuration is intended for compatible marine spotlights, bunk lights, reading lights, and chart lights with vertically oriented G4\/GU4 sockets. Its relatively wide circuit board makes fixture clearance an important consideration when replacing an existing bulb.\u003c\/p\u003e\u003cp\u003eBefore installation, verify the socket orientation, pin alignment, available internal clearance, and electrical supply. The back-pin arrangement differs from side-pin LED bulbs, so matching the existing socket configuration is necessary for proper installation.\u003c\/p\u003e\n\u003cspan itemprop=\"mpn\" hidden\u003eILBPG4-21W-B\u003c\/span\u003e","brand":"Imtra","offers":[{"title":"Default Title","offer_id":52063231541494,"sku":"APL119066","price":15.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0809\/6658\/2518\/files\/Circular_LED_PCB_Module_with_Twin_Pins-optimized.webp?v=1793199545","url":"https:\/\/www.apollolighting.com\/products\/apl119066","provider":"Apollo Lighting","version":"1.0","type":"link"}
