26 LC DBM BRINGING INTO THE W When Michael Sestak, owner of Sestak Lighting Design in Carmichael, California, was asked to fix the outdoor lighting at a home near Sacramento, he first inspected the existing system and after finding broken lamps, cut wiring and other deficien- cies, the need for an entirely new system became obvious. His clients felt like they had lived with troublesome lighting long enough and not only that, Sestak saw an opportunity to introduce lighting that changed color, especially for two groups of palm trees in the backyard. Above Michael Sestak, principal of Sestak Lighting Design, overhauled the outdoor lighting system for a home in Elk Grove, California. After he realized an entirely new lighting system was required, he selected one that could mix colored lights and white light through the use of two different LED chips: ZD (zoning and dimming) and ZDC (zoning and dimming + color). Two groups of palm trees near the pool and spa are illuminated with uplights with ZDC. With the controller, the homeowner can change the hue, saturation, and intensity settings of each fixture or group of fixtures. The sys- tem's program operates automatically, and controls more than just on/off times. The homeowner can change from one color palette to another with a tap on a smart device, and can choose from dozens of combinations in a "library" set up for the client. "The fixtures using the ZDC LED chips are zoned together, so the effect on the palm trees is uniform," Sestak said. The controller sends signals out to each fixture (or group of fixtures) through the standard wires used to power the fixtures. "Each fixture has its own address," Sestak said. "The brain inside the controller allows the contractor to completely tailor the system to the client's needs with various scenes whether entertaining a large group for a BBQ or for simply relaxing in the spa." He advises contractors to visit http://www.fxl. com/zdc to see how the system works. COLOR MIX By Michael Miyamoto, LC/DBM
