Meet the AURA: a set of wirelessly powered Christmas lights you can control from your smartphone. You get LED lights that could last you up to 20 years. You get a ring light that that provides the energy the lights need wirelessly. The companion app for this system lets you control your lights form your iOS or Android device.
To put AURA to use, just snap the Power Ring onto your tree, plug it into your wall, and place the Aura wireless lights on your Christmas tree. AURA wireless lights will be available in clear, crackle, and frosted glass versions. You can find these lights on Kickstarter.
