The Navigation Morse Signal Light, with its robust brass body and engineering plastic lampshade, is designed for maritime communication. This particular model, the CXD7-B, is equipped with a B22d lamp holder and utilizes a 2*25W power setup with an incandescent lamp, ensuring a bright and clear signal. The light's white color is standard for such signaling devices, providing maximum visibility. With a horizontal arc of 360°, it offers an all-around range, making it visible up to 5 nautical miles, which is essential for long-distance communication at sea. The device's protection class of IP56 indicates that it is well-protected against dust and powerful water jets, making it suitable for the harsh marine environment. It can operate in a wide range of temperatures, from -30℃ to +55℃, which is crucial for vessels traversing different climate zones. The installation method is seat-mounted type, which is a common and secure way to install such equipment on ships. The cable's outside diameter accommodation ranges from Φ12 to Φ14, providing flexibility for various installation needs. Weighing in at 4.9kg, it is relatively lightweight for its durable construction. This combination of features makes the CXD7-B an efficient and reliable choice for maritime navigation and communication.
