The VLB-44 is a lighthouse optical system designed and built by Vega Industries Ltd. in Porirua, New Zealand. [1]
The VLB-44 consists of one to eight tiers of LED bulb assemblies. Each tier draws approximately ten Watts. The tiers are available in 3 vertical divergences:
They are available in white, red, green, blue, and yellow.
The light output and timing is controlled within tight limits. All of the features, including characteristic, day/night transition time, and synchronization is programmable with an IR programmer. The units are expected to have a service life greater than ten years, depending on characteristic and duty cycle. [1]
From the first use of lighthouses with flashing lights, the light source has been continuous. Turning a flame on and off was impractical and flashing an incandescent electric lamp reduces its life substantially. The characteristic seen by the observer has been achieved by rotating a lens system. Since LEDs can be flashed on and off without degrading their lives, it appears that the use of rotating beacons in lighthouses is coming to an end. [2]
