ACR 55W Replacement Bulb f/RCL-100 Searchlight - 12V

The ACR 55W Replacement Bulb f/RCL-100 Searchlight is a high-intensity marine lighting component engineered for serious boaters and commercial operators who depend on reliable night-time visibility on the water. This 12V halogen bulb serves as a drop-in replacement for ACR's RCL-100 series searchlights, restoring full brightness output when the original bulb dims or fails. Whether you're navigating coastal waters, conducting search and rescue operations, or positioning your vessel during night docking, a properly functioning searchlight is non-negotiable for safety and operational efficiency.

At 55 watts of halogen output, this bulb delivers the intense, focused beam characteristic of quality marine searchlights without excessive current draw on 12V systems. The halogen element provides superior color temperature and lumen output compared to standard incandescent alternatives, cutting through fog, rain, and darkness with sharp definition. Its compact 1-inch diameter and 4-inch length fit precisely within ACR's RCL-100, RCL-100A, RCL-100B, RCL-100C, and RCL-100D searchlight housings, ensuring correct optical focus and beam pattern. The bulb weighs only 0.1 pounds, maintaining the balance and handling characteristics of your installed searchlight assembly.

Commercial fishermen, charter captains, and search-and-rescue teams benefit most from stocking replacement bulbs onboard, as marine searchlights operate in demanding salt-air and high-usage environments that accelerate bulb degradation. Installation is straightforward—simply power down the searchlight, allow the housing to cool, and swap the old bulb with this new unit, ensuring proper seating in the fixture. This individual bulb is sold as a single unit, making it ideal for emergency replacement or preventive maintenance. Keep one in your galley for reliable night operations year-round.
