The VRB-25 LED is a high intensity rotating beacon suitable for ranges up to 25 nautical miles. Being an LED beacon, it is extremely energy efficient and can be monitored digitally.
It is an ideal replacement for beacons with Fresnel lenses in historic lighthouses, or locations requiring intensities greater than what can be achieved with typical stationary beacons.

Functionaltity and Features VRB-25

The VRB-25 LED has unique advantages over other stationary beacons: There is no lamp replacement or maintenance required, as the LED beacon will operate for over 70,000 hours. Traditional lighting such as halogen bulbs, metal-halide lamps or fluorescent tubes have lifespans under 4,000 hours.

Rotating beacons provide greater intensities with lower power consumption than stationary beacons. As the light is focussed into narrow beams instead of going in all directions at once, it is brighter. Each white LED produces over 520,000cd. When rotating at 1 RPM, the effective intensity is 209,000cd. Depending on rotation speed, the 4 tier beacon is visible up to 25NM (or 40NM at 0.85T).

The VRB-25 LED maintains the traditional beam of light sweeping through the sky, with the unique build-up and fade-out of brightness which is associ-ated with lighthouses. This effect was lost with stationary LED beacons.

The VRB-25 LED is ideal for solar-powered applica-tions. Solar panels and batteries can be 80% smaller than was previously required. The VRB-25’s brush-less motor only consumes 1.2W of power and each LED tier uses 22.7W (6 panel).

Flash characters are produced by setting the rotation speed and selecting 6 or 8 optic panels. Group flashes can be achieved by ordering the VRB-25 with blanking panels instead of LEDs. LED panels can also be disabled if required.
