Ketra specializes in bringing natural light to indoor spaces. With the ability to generate a wider gamut of color via precision optics, Ketra’s technology allows light to be tailored to every room and its purpose. The result is a more comfortable atmosphere, and improved overall wellness.

The Problem with Poor Lighting

We’ve all strained our eyes through inadequate lighting, or squinted through lighting overkill. Less often discussed is the huge impact color temperature can have. Indoor light feels “right” when it matches natural light as closely as possible. The blue hue of a rising sun, a warm sunset, the low flicker of a candle flame… These natural sources trigger emotional and biological reactions from us all. A contrast between our indoor lighting and the natural light around us can cause measurable discomfort.

Ketra’s Solution

Most lights offer a single color. Others mix red, green and blue sources to offer a wide range of color estimations. Ketra, however, has designed custom chip drivers in their lamps to provide the highest quality, most accurate light source across a full range of colors. Each Ketra fixture can then be individually tuned to the area around it, for a more precise lighting design throughout the space. Each fixture can then be programmed to adjust through the day automatically, matching the sun’s temperature as it rises and falls.

Ketra’s various luminaires and lamps use custom silicon domes made to utilize precision optics. Precision optics help highlight a space’s architecture and furnishings with uniformity of color and intensity – free from distortion and unwanted reflections. While traditional optics have proved sufficient for single color points, Ketra’s full spectrum requires a more advanced approach. They start by packing their LEDs as closely as possible under a silicone dome, then align the light via a reflector optic. Finally, a secondary pillow lens smooths out the beam before it spreads into the room.

The Impact

At Cloud9, we believe that natural lighting will improve the space, but more importantly your overall wellness. Harsh lighting can impair focus. Cooler lighting can keep your body alert when you should be relaxing, while warmer light can do the opposite. It’s important to let ourselves thrive through the day and rest in the evening. Ketra’s technology produces dynamic, high-quality light that helps you feel more connected to nature. A well-lit space can mean a more comfortable work, living and headspace.

The Demo

Of all the lifestyle technology we install in the homes of our clients, the most dramatic impact on lifestyle (and the most dramatic reaction when demoed) is probably from Ketra. The flaws we’ve come to normalize in indoor lighting suddenly become glaringly obvious when seeing Ketra’s full spectrum lighting experience against normal LED or halogen lighting.
