Pentair 580001B MagicStream LED Laminar, 100 Foot Cord, Requires 12V Power, Black Lid Laminar water streams can reach up to 7-feet high and project outward up to 8-feet into your pool, spa, or other water feature Nighttime lighting effects include the ability to hold on a steady color or scroll through a range of colors Installation is made flush to your deck or other surface; no unsightly or unsafe edges, just the magic of water erupting from a hidden source Water streams are easily adjusted in two ways- vertically from 62 degrees to 75 degrees to create different heights and arc shapes LED Laminars include 100-feet of electrical cable; simply connect to a 120/12VAC-100-Watt pool lighting transformer to provide power.The technical principle behind MagicStream Laminars is to remove all turbulence and air bubbles from the water before projecting it through a finely machined nozzle; the laminar water flow is very nonturbulent, so it keeps its surface tension and flows through the air in a smooth, clean, unbroken stream, instead of spraying apart into droplets
