Lumations branded led that use Twinkly app. Comes with 600 Rgb Led Christmas Lights at $199 from Costco.
I could see kids having lots of fun with these. At least that's what I'll tell my wife.
These are not the genuine twinkly branded lights. Twinkly branded 600 LEDs are $400 but still use the same app.
Can you schedule power on/off etc? How does it know where the lights are situated on the tree?
