Does excellent lighting work, surprisingly resilient to power surges and surges due to wiring issues that have been poorly documented. I am very happy with our choice of lighting. It occupies a large space that could one day host a group yoga class. My job is to provide good lighting and monitor the installation. My wife is interested in yoga classes. I recommend these lights as a modern replacement for glass spotlights. The whole product seems well thought out. Choosing 5 different color temperatures was a lot easier than trying to match the color of the lighting from the pictures.
