Definition of Spotlight

A spotlight is a type of directional light fixture that emits a narrow, intense beam of light in a specific direction. The narrow condensed beam of spotlights also provides light over a longer distance than wider beams.

Spotlight fixtures can be adjustable or recessed.

Spotlights are therefore ideal for:

  • Accent lighting, highlighting special objects or features of a space, such as bespoke joinery in a yacht
  • Search lights that identify lost objects or people in the water
  • Navigation lights, which contribute to marine safety by informing other boats about one’s location, size, and direction
  • Task lighting, for example, bait rigging after dark or inspecting your tackle

The following factors affect the usage and effectiveness of a spotlight:

  • Beam angle: The narrower the beam angle of a bulb, the farther away it’s light reaches
  • Color temperature: The color of the light emitted affects its brightness and effectiveness. For instance, a cool white light provides brighter illumination than a yellow light of the same wattage
  • Bulb type: Different bulb types offer different levels of brightness and energy efficiency
  • Power source: Some spotlights are hardwired while others are powered by batteries
  • Material and design: For a spotlight to work efficiently on a boat, it needs to be of marine grade
