Heelight, a smart light bulb designed and produced by MicroNovelty, does more than just illuminate.

It can “hear” its environment and generate an impressive range of functions and colours, programmable via an app.

In need of a tranquil ambience? Choose “ocean” and watch the bulb gently cycle through 12 shades of blue. Proposing a champagne toast at a dinner party? Initiate “clink” mode and see the bulb flash every time it picks up the sound of chiming glassware.

Want to see what your room would look like bathed in the glow of candlelight, but don’t want the fire risk? Heelight has a “candle” setting, with a neat function that lets you extinguish the bulb by blowing directly on to it.

Heelight also has a host of more quirky modes, including “coward”, which flashes when you scream at the bulb; “warning light”, which mimics a blue and red flashing siren; and even a “sex” mode, a lusty pink glow that glows brighter when the bulb hears, ahem, sounds.

“It even has pumpkin mode,” MicroNovelty founder and chief executive Oliver Sun says proudly. With a tap of the app, the bulb switches to a festive orange for a few moments before beginning to flicker spookily. A single handclap from Sun causes it to snap back to its original steady glow.
