I love the Phillips Hue Lily and Lily XL, but the price certainly is up there.
I have RGBCCT light strips set up along the “rock wall” but have low voltage wiring ready to go as well.
One idea is some MR16 bulbs inside a fixture, but I’m open to ideas. While I prefer something “ready to go”, my priority is durability, tunable whites + color, and seamless integration with HA.
