Up to 4 nautical miles (7.4 km)
The Model M704-5 4-NM (7.4 km) solar-powered LED lanterns are the world's most advanced, solar-powered LED navigational and hazard-marking lanterns. They are completely self-contained, install in minutes and require no maintenance or servicing for up to to five years.
The Model M704-5 is built for performance in harsh weather conditions. The Model M704-5 uses an array of ultra bright LEDs and can be programmed with over 200 flash patterns. Manufactured in accordance with ISO 9001:2000 Quality Assurance Standards, the Model M704-5 produces light output in IALA's four international chromaticity colors: green, red, amber and white.
Through the innovative combination of solar power and LED technology, the M704-5 lanterns charges during the day, even under cloudy conditions, and turn on automatically at night. Instead of relying on short-lived incandescent bulbs, the M704-5 uses durable, ultra bright light emitting diodes (LEDs), which have an operating lifespan of up to 100,000 hours. Our new optics and lens design mean wider vertical ivergence and greater light uniformity.
