Alexa now works with Sengled carbon neutral LED bulbs
allows Alexa owners to directly control the lights with voice commands such as "Alexa, dim the bedroom lights" or "Alexa, turn on the kitchen lights." Alexa can also control numerous other smart lighting systems, such as Philips Hue, Cree and GE. Only Sengled will plant a tree for every bulb you buy, however. That promise, in partnership with nonprofit One Tree Planted, makes the usage of the bulb carbon neutral for its lifespan, according to the company.
