"The innovative device with the working title MicroMiner was introduced last June and has been in development since then. It has two chips built inside it: one providing Wi-Fi and the other running bitcoin mining operations. The MicroMiner light bulb is the first Internet of Things device of this kind."

Is the heat generated from mining operation used to light the bulb?
