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.
