Our Make a Splash event in New York was a success, drawing lighting design professionals from across the industry to dive deep into the principles of underwater lighting. The event provided a unique, hands-on learning experience that emphasized both the technical and aesthetic aspects of underwater lighting for aquatic environments.

Exploring the Science of Light in Water

One of the primary topics covered was the science behind light transmission in water, including essential concepts like reflection, refraction, and absorption. Attendees learned how these principles affect how light behaves underwater, impacting both safety and visual appeal. Reflection refers to light bouncing off surfaces like the water surface or pool walls, while refraction is the bending of light as it enters different mediums. Absorption, on the other hand, affects how different wavelengths of light penetrate water, which is why we see blue tones dominate underwater environments.

Creating Functional and Safe Pool Lighting Designs

The workshop then shifted focus to practical design considerations. Ensuring safety was a top priority, with guidance on illuminating critical areas, such as pool steps, entrances, and exits. Proper lighting in these areas reduces risks while enhancing the overall user experience. Additionally, the workshop explored how lighting placement and techniques help create the desired ambiance without causing unnecessary glare.

Design Factors Affecting Light Perception

Different finishes, whether light or dark, dramatically impact the look and feel of an underwater space. Lighter finishes reflect more light, creating a bright, open effect, while darker finishes absorb light, giving the pool a more intimate, atmospheric feel. The pool’s shape and fixture placement are also crucial, as irregular shapes can cast unique shadows and enhance visual interest. Wider pools often require additional fixtures to ensure even coverage and prevent dark spots.

Light Intensity and Glare Control

Adjusting lighting intensity to account for ambient light from the sky, choosing suitable color temperatures, and implementing glare control measures like Half Moon and Honeycomb and Honeymoon shielding were all demonstrated. These techniques are invaluable in creating a balanced, visually appealing aquatic environment.

Looking Forward

We extend our heartfelt thanks to Lightabilities for their support in bringing this event to life and to all attendees who contributed their insights and enthusiasm. Events like Make a Splash are at the core of our mission at Filix—to advance lighting design through collaboration, innovation, and education.
