What Buyers Say
Setup was a breeze with HomeKit, and the colors are vibrant. Works perfectly with Siri shortcuts and automations. Highly recommend for anyone starting out with smart lighting.
Love the Thread connectivity and how responsive it is compared to my old Bluetooth-only bulbs. Occasionally there's a slight delay when controlling several at once, but overall very happy.
The bulb itself performs great — bright, colorful, and reliable. The Nanoleaf app could use some polish though, especially for creating custom scenes and schedules.
I have several of these throughout my house now. They integrate seamlessly with my HomeKit setup and the circadian lighting feature is a nice touch for winding down at night.
