Used @rain ginkgo's Dig COB 24V LEDs with 3D printed sleeving to create a nice ambiance for our backyard. Compliments string lights very well! Happy to share the files if theres interest.
They are designed with a high cutoff angle, so from most of the backyard they are invisible and only the puddle of light is visible on the ground. Then when underneath them the bright and well defined lasers appear!
