Plantscape Solutions is now installing WAC Landscape Lights. These LED low voltage lights offer beam spread adjustment and lumen output adjustments on each fixture.
This really allows you to fine tune the lights to fit each specific location they are installed. As trees or other planting material gets larger you can adjust for this growth.
Some fixtures even have kelvin temperature adjustments to allow you to use either 2700 or 3000 kelvin temperatures.
If you really want the ultimate in landscape lighting there are even color changing lights that work with apps on your phone. Set colors for different holidays, birthday parties, or many other occasions.
