How many lumens do I need to uplight a tree?

For smaller trees up to 1 story or 6-10 feet, opt for 80-120 lumens. This level is the lowest lumen level and also works great for bushes and shrubs. For medium-sized trees up to 2 stories, go with 140-180 lumens. Larger trees up to 3 stories require 230-270 lumens. Feb 23, 2022
