Operating on 10-30VDC with a 3.0W power draw, it delivers 270 lumens through 21 surface-mounted LEDs, making it suitable for larger overhead lights, spot fixtures, and utility lighting.\u003c\/p\u003e\u003cp\u003eThe bulb uses a constant-current driver to maintain consistent light output across its operating voltage range. Its wide circular circuit board distributes the LEDs over a larger surface, while the side-pin configuration accommodates fixtures with horizontally oriented G4 sockets.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e10-30VDC operating range for compatible 12V and 24V DC systems.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e3.0W power consumption with 270-lumen cool white output.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e21 high-output surface-mounted LEDs.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eG4 side bi-pin connection for compatible light fixtures.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eConstant-current driver for stable illumination across the supported voltage range.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eWide circular LED board for larger spot and overhead fixtures.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and installation\u003c\/h6\u003e\u003cp\u003eThis replacement bulb fits G4 fixtures with side-entry pin connections, including compatible marine overhead and utility lights.
