The Masthead Navigation Signal Light, with a 30W power rating and Type CXH3-2S, is an essential marine navigational equipment designed to ensure the visibility of vessels on the water. Operating at a rated voltage of DC 24V, this signal light uses an incandescent lamp as its illuminant, providing a bright white color that is visible up to 5 nautical miles. The light covers a horizontal arc of 225 degrees and a vertical arc of +5 degrees, which is crucial for conveying the vessel's position and orientation to other seafarers, especially during night navigation or in poor visibility conditions. The robust construction of the light, featuring a stainless steel body and a PC engineering plastic shade, ensures durability and resistance to harsh marine environments, with a protection class of IP56 indicating a strong defense against dust and heavy seas. The lamp can be easily installed in a seat-mounted fashion and is designed to operate within a wide range of ambient temperatures, from -30C to +55C, making it suitable for a variety of climatic conditions. The lamp shade is available in transparent, red, green, and yellow colors, providing options for different signaling requirements. Weighing only 1.5 kg, it is a lightweight yet reliable choice for maritime navigation safety.
