Meet the LIGHTIFY Gardenspot Mini RGB from Osram: a WiFi enabled and app controlled system that lets you light up your garden. It comes with a WeMo Link, allowing you to connect up to 50 lights and control them individually and as a group. Whether you want to make your garden glow at night or change the mood of your party, these garden lights have you covered.
The companion app lets you adjust colors, turn your lights on, and do a whole lot more from your smartphone. The lights can be mounted on the ground or to a wall. They are wet-rated for outdoor use. More information is available here.
