Landscape lighting has come a long way in recent years. Propelled by super-efficient LED lamps (for both new and existing systems). The big advantages of LED fixtures is the lights ability to take a variation in voltage cause by length of the line and the longevity of the LED lamp. The first LEDs were blue in color and rather expensive, both of those things have changed. Transformers have become more sophisticated with timers that adjust not only for daylight savings but, also to longer and shorter days. Lights that are build into retaining walls, columns and steps can add definition to to those features as well as make it safer.
Some more elaborate systems can adjust/dim light levels, control individual lights, be controlled from your phone and even change colors. How about “setting up your holiday décor” by simply adjusting your landscape light colors via your smart phone!
