The VLB-5-SA is the standalone version of the VLB-5. The light is designed for applications requiring a 2 to 4NM range at 0.74T and available in red, green, white, yellow and blue. All colours meet the IALA chromaticity requirements.
The VLB-5 LED beacon is available in 2 standalone models; VLB-5SA (standalone) 12v for use with external DC power supply and the VLB-5SAM (standalone mains) for use with external AC power supply. This was previously named the VLB-67.
The use of highly efficient optics and electronics has resulted in high energy efficiency. The low energy needs of the beacon reduce the solar panel and battery requirements in the overall design. Vertical divergence of the lens at 50% of the peak intensity is better than 7 degrees.
Vega provide a VLB-5 calculator on their web site to determine the supported range for different flash characters dependant on location. See Vega VLB-67 Calculator.
