The SKY is a 200w, LED aquarium light, with patented diffuser technology, that smoothly blends all of its 104 LEDs to create a homogeneous field of coral-health-optimized light — no hotspots, no disco-ball effect, no need to augment it with other lights or add-on diffusers — but best of all, none of the harsh shadowing and fractured spectrum found in most other popular lights. SPREAD Bathes the aquarium in light, minimizing shadowing. SPECTRUM Optimized for coral growth and color, well-blended, and pleasing to the eye. SIMPLE Coral growth and success without a complicated interface Diffused light just like what illuminates planet Earth. . . The earth is illuminated by the sun, but not as a single point of light like a light bulb. If it were, there would be harsh shadows and the reefs as we know them would likely not exist. Instead, our planet is really illuminated by our atmosphere, the sky, as a filter and diffuser of the sun’s rays. This results in a homogeneous, bathing of light from all directions. The SKY brings to your aquarium that blanket of natural and life-sustaining light that nourishes earth’s coral reefs. While a few prefer the natural look the sun and sky provide on natural reefs, most tend to appreciate a more blue-purple light in various degrees. But the desired aesthetic is not universal. So the SKY delivers both. It can be easily tuned to the unique “look” that individual reef-keepers desire, without sacrificing the quality of the life-giving light the corals and other animals need.

For proper coral growth and health, this is something we attempt to accomplish in our reef aquariums. Unfortunately most LED reef lights have a small surface area of light origination that creates dark areas and harsh shadows – sometimes with an altered spectrum. As a reef aquarium matures, this is the main limiting factor for coral growth and health. Many attempt to correct this deficiency by adding additional fixtures, light-limiting diffusers, additional fixtures or hodge-podge together a hybrid solution with supplemental lighting strips. The SKY has a large surface area of diffused light at the origin which emulates the horizon to horizon effect of the atmosphere and minimizes shadowing. The SKY alone is all you need to properly light your reef aquarium and provide for the health, growth, and color needs of even the most demanding corals. SPECTRUM - BLENDED AND UNIFORMLY DELIVERED Do LED lights grow healthy, colorful corals? Of course. But to be optimal, they must have the right spectral balance of colors, sometimes referred to as “full-spectrum”. Also, and more importantly, that light must be blended and spread uniformly over the entire aquarium. All full-spectrum, LED reef aquarium lights mix various discrete LED colors, each one with its own segment of the spectrum, along with whites. Blending all these LED together into homogenous light is where things get tricky. Some light designs bring all the LED very close together so that they blend at the source. The downside here is this very small area of light origination creates the harshest of shadows. Others spread out LED, hoping to mix the various spectrums of the discrete LED on their way to the aquarium – but this leads to the “disco-ball ” or “static” effect we often see in the shadows or on the sand in the aquariums. The SKY has 104 carefully curated LED, split into four controllable channels, spread across a large surface to maximize the area of light origination and minimize shadowing. Then the SKY uses patented light engine technology that mixes some of the light from all the LED right inside the light panel. Then that light, along with some of the direct light from the LED, all pass through a carefully selected diffuser panel that evens out all the light while minimally reducing the light output. The result is a well-blended light output, that has the same spectrum, nearly everywhere in the aquarium, with minimal shadowing and no disco-ball-effect.
