The Searchlight 2*575W Type SD-4 is a robust and versatile lighting solution designed for demanding environments. With a rated voltage of AC220V and a power factor of ≥0.9, it ensures efficient operation. The dual 575W illuminants, capable of using both HMI and Ultraviolet light, offer a high color temperature of 6000K, providing bright and clear illumination over great distances—exceeding 6000 meters with standard light and 4000 meters when utilizing ultraviolet light. The manual or electric adjustment allows for unrestricted rotation, offering flexibility in directing the light where it is most needed. The searchlight's protection class of IP66 signifies its dust-tight and powerful water jet-resistant construction, making it suitable for outdoor use in various weather conditions. The cable's outside diameter compatibility ranges from Φ6 to Φ12, accommodating different installation needs. Designed to be seat-mounted, it can withstand ambient temperatures ranging from -30℃ to +55℃, ensuring reliability in extreme conditions. The lamp body is made of stainless steel, and the lampshade of toughened glass, which can be equipped with ultraviolet glass for specialized applications. Weighing 80kg, it comes with a controller power box that includes standard functions such as focusing, lamp life timing, fault alarm, angle display, and speed adjustment, with an optional heating function to maintain performance in cold environments. This searchlight is a testament to engineering designed to meet the rigorous demands of maritime and other industrial applications.
