Smart color light bulbs—LED-based bulbs that can be controlled by a smartphone and “tuned” to emit any hue in the rainbow—are no longer a new idea. What is new is how far this technology has come since its advent just a few years ago. Also new: Products like the Nanoleaf Aurora that fundamentally change the light bulb concept. Aurora is a system of interlocking LED panels that let you decorate with light. You'll find our review here.
Color LED bulbs aren’t quite a commodity yet, but they are getting close to maturity as far as the market goes (the Aurora being an exception). Today’s bulbs are more compact, much brighter, have better color representation, and, for the most part, feature control apps that do more than ever, and are easier to set up. Prices have also come down, with some no-name color-tunable bulbs now available for less than $10 each. (Buyer beware: You get what you pay for.)
