This is a 2 part request (front and backyard). In the front I have an existing kit (https://www.voltlighting.com/landscape-lighting-kits-complete/c/11) w a 100W transformer that came w my kit rather than the current 150W transformer in the current offering. I'm planning on reallocating the current 100W transformer to the backyard and getting a bigger one for the front. My current setup is in yellow. What I'm thinking; spot lights in green (what type and angle?), flood lights in light blue (type and angle?), and pathway lights in pink (wattage?).
For path lights, 3W 2700K is the most popular for a balanced combination of subtle yet functional illumination. If you wanted a more subtle output with those path lights being out in the yard for illuminating the bed, a 2W would look beautiful as well. For the trees near the path lights and in back, you could consider the popular Integrated Big Splash Flood Light or the Gentle Splash Flood Light with a 3W LED for a more subtle option. For the larger tree near the front door, a more powerful fixture with more dispersed illumination like the Wide Splash R7S Flood Light would highlight the tree beautifully while likely providing a beautiful shadowing effect on the exterior wall behind the tree.
