Uplighting means simply using grounded lamps to direct light up at the trunk or canopy of a tree in your landscape.
Uplighting pine trees. The larger the tree the further back the directional up light will need to be to capture the tree. Level forever unless someone physically moves it. Level 3 230-270 lumens.
Contrary to popular belief if a fixture is placed at a 20 ft level in the tree it will remain at that 20 ft. This upright grower maintains its tight and formal shape without pruning. Instead denser trees should be lit from the outside of their canopy.
The Columnar Colorado Blue Spruce 25 7 is a spire of steely blue foliage that can slip into any sunny spot in your landscape. Uplighting that stand of pine trees and your pretty red bud tree. We might light the columns on the front of your home and those striking timber gables 20 feet away but what about the spots in between.
By comparison downlighting is subtle and can create an inviting outdoor living space. Bullet accent lights with 20-watt halogens about 62. Using metal halide uplights with a 36 beam angle are ideal for lighting up narrow trees such as Silver Birch and Scots Pine trees.
A 50-foot tree may require three to five uplights of 35 to 50 watts apiece. Annual cycles of growth and reproduction in trees controlled by day length can potentially be altered by supplemental night lighting. In uplighting landscape lights are mounted below or at ground level shining the light upward.
Level 4 350 to 1000 lumens. Trees less than 20 feet tall need only a couple of 20-watt uplights. When uplighting a tree the shape and density of the tree should be heavily considered.
