Spot Beam


Definition of Spot Beam

A spot beam provides a focused and intense illumination in a specific area. Spot beams project light over a long distance with a narrow beam angle, making them fantastic for search lights, signal lights and task lighting.

The beam angle of a spot beam is usually 30 degrees and the field of light maxes out at a 60-degree field angle.

Lighting fixtures that employ spot beams are ideal for navigational lights because of their long range of visibility, but it’s important to ensure that they meet regulatory requirements.

They are also ideal for task lighting on the boat and accent lighting. LED lights dominate the field of spotlighting because they have a super condensed, directional beam.

A particularly beautiful application of spot beam lighting is underwater boat lights, such as the SeaBlaze X2 LED Underwater Light.
