In this review we're going to check out an A-19 style LED light bulb that has a Zigbee radio inside, so that it can be controlled by popular home automation controllers. Typical LED bulbs have gotten very inexpensive lately, with high quality bulbs costing just a couple bucks. That the manufacturer, Sengled, can offer what looks like a decent quality LED bulb with a Zigbee radio inside for $9 with Amazon Prime free shipping, does seem rather impressive.
