Preferred Properties Landscaping has brought new light to lighting timers and control through controlscape modules. Smart timer controls all the transformers in the landscape from inside with the touch of a button. Smart sensor tracks sunrise and sunset via latitude and longitude and you simply set the default for the lighting to turn on and can extend times from inside. No longer are your timers interupted by power outages. Its outrageous and brings great value to an already existing component. Great for security and convenience.
