The Aquatop SkyAqua SAQ-1218 raises the bar for aquarium keepers by combining style and technology. Each specially engineered light mimics the shimmer of natural sunlight, produces minimal heat, offers a fanless design for pin drop silence, and provides general illumination for your aquatic organisms. The SkyAqua LED light can fit on virtually any tank from 12 to 18 inches for a quick, low profile installation.
