Currently testing all my fixtures. Decided to wash our brick walls and move some shrubs away from the foundation before installing our lighting (ok, I'm a wee bit of a perfectionist sometimes). Meanwhile, I'm second guessing my initial idea for fixture placement and beam spread choice for lighting the 30' H oak with a 25' diameter which sits in the dead center of my front yard. I'd originally planned to flank the base of the tree with two 38° All Stars (one in front and one in back) and a pair of 60° Salty Dog well lights in the locations shown on the diagrammed photo. Problem is, because there's no sidewalk, the fixtures would have to tolerate a fair amount of foot traffic. Even though these are solid brass and I'm sure quite durable, I'd really prefer not to put them to the test. Which brings me to my challenge: Is there a preferred/ideal way to light a tree of this size while keeping all of the fixtures more or less within the drip line of the tree? In my diagram of the tree canopy (where the stars = All Stars and the letters indicate different outer light placement options), would any/all of these layouts work? Will the 60° beam spread sufficiently illuminate the canopy or should I go with 110° bulbs? I've purchased enough fixtures to proceed with any of these approaches.
