Brilliance LED BRI-SECTOR-SELECTOR Sector Selector. Use the Brilliance Sector Selector to create specific sectors or zones that can be controlled independently from a single transformer. The Sector Selector can split a single transformer into four separate zones with up to 200 watts to each sector. Use these zones to separate lighting schedules and scenarios to create special scenes or layers of light in your landscaping. For example, separate a front yard from a back yard, or independently control lighting for water/architectural features, outdoor kitchens, around pool and spa areas, outdoor decks or seating areas, or path and garden lighting.
