A marine searchlight has to be capable of performing a range of tasks from locating buoys to illuminating a narrow channel and unfortunately, occasionally searching for a man overboard. To this end it needs to be designed to offer the best combination of beam spread (width) and intensity (length), for both shorter and longer range work.
A spot beam has a 7° beam spread as opposed to 40° on a flood beam and will consequently reach at least 3 times further. Sometimes a searchlight beam is defined at 2° but for anything less than a large stable ship this is not usable, being difficult to aim and offering too concentrated a beam for effective sweeping when mounted on a small craft. We quote performance of our searchlight range in two ways; Candlepower and Lux.
Candlepower is a useful guide to actual light produced but doesn’t measure the efficiency of reflector design to actually project that light at the target. The most relevant comparison guide is LUX, which is the measurement of actual light available at a given distance (we quote at 100 and 500 metres (330ft - 1650ft)
Remote Control Searchlights are suitable for craft from 5m (16.4ft) upwards, and their main advantage is that they allow the light to be situated away from the helm in a position of maximum effectiveness. Control is via an eight way joystick and a Secondary Remote Control Kit is available for most lights allowing control from both flybridge and saloon.
Floodlights illuminate deck areas or can be mounted in the stern to provide a wide beam spread for local area lighting. |
