Range: 7 - 23NM at 0.74T
Ideal for: port & harbour range light applications
The rugged FA-240 Range Light meets all the requirements of a unidirectional modern aid to navigation. It produces a high intensity light in a relatively narrow beam from low wattage.
A two station range makes it possible for the mariner to navigate the center of a restricted channel. The lights of each station, front and rear, are aligned when the ship is on the channel's centerline. The lights separate when the ship drifts to either side. This feature gives the pilot a “feel” for his position off the range since he can tell the direction and degree of drift. Course correction can be evaluated immediately by whether the lights begin to "close" or continue to "open."
However, with a single station polychrome range, the pilot knows only if he is in the center of the channel or to one side or the other. There is no indication of degree of navigation error. Also, he’s unable to determine if the ship's position is improving or worsening.
- ECONOMICAL: Short-filament 6 or 12 volt lamps give high beam candlepower from low wattage. A four or six place automatic lampchanger eliminates the need for duplexing.
- FLEXIBLE: Lightweight and compact construction, rifle type aiming sights, and leveling and aligning adjustments in the base simplify installation. A flat pad on top of the housing provides a convenient position for a circular spirit level. All components are easily accessible when the back cover is removed from the housing.
- EASY TO INSTALL AND SERVICE: The FA-240 Range Light is available with solid-state flashers for any flash characteristic, and with either four or six place lampchangers. Space is provided in the housing for a sun switch. There is also space in the base for a transformer if AC input is desired.
- SELECTION OF LENS AND LAMPS: Both “Flatlite” and “Spredlite” lenses of red, green, yellow or clear are available. A flat lens gives a very narrow beam of high candlepower, while spredlite lenses give a higher divergence to the beam. The degree of divergence selected will depend on the points at either side of the channel from which approaching vessels should first see the lights distinctly. Lamp sizes are available to give the desired range of visibility, taking into consideration the color of the lens and normal atmospheric conditions.
