VSL-73 Precision All Around LED Sector Light

AVAILABLE FROM 4 TO 10NM RANGE @ 0.74T

The VSL-73 Sector Light forms part of the Vega LED marine beacon family and is designed for omni-directional applications where precision sectoring is required. The VSL-73 provides a LED alternative for shadow casting sector lights using incandescent lamps. The VSL-73 can be used for sector light applications ranging from 4NM to 10NM with a normal visibility of 10NM (0.74T).

Each VSL-73 is customized for the particular applications taking into account the required range, colours, and sector angles. Mechanically the VSL-73 is available in any combination of subunit (half unit) and full unit up to a maximum of a 3 unit high version. A full unit consists of 6-lens layers that can be the same or made up from different colours. A full unit in one colour will typically have a range of 10NM at 0.74T.

The sector angles are created using a mask fitted inside the outer acrylic wall. This provides a beacon that is suitable for outside use (IP67) and is easy to install and align. The customer is provided a base mounting drawing detailing the mounting relative to true north. A rotational adjustment of ±5° is provided on the VSL-73 for on site sector alignment.

To maximize energy efficiency only the LEDs required for the sectoring are used. This reduces the cost for any solar powered applications.

Standard colours are white, red, and green. For other colours please refer to Vega. All colours meet IALA chromaticity requirements.
