You would have to buy special light bulbs anyhow, you won&#x27;t be able to use a commercial of the shelf bulb for this no matter what the BBC thinks.<p>The LED&#x27;s need to be able to turn on and off in nano-seconds so you can&#x27;t just twitch the AC power because the voltage regulator will not respond fast enough (there is enough juice in the capacitors to drive the LED&#x27;s for a few seconds usually this is why cheap LED light bulbs don&#x27;t turn off straight away, the more expensive ones have usually have a current shunt that will clear the capacitors to ground when you hit the light switch) and most likely simply die after a few minutes.<p>So you need to do in-circuit modulation which means a dedicated light bulb.<p>Well in theory you start building light bulbs that can be effectively turned on and off about about a billion times a second which is not going to happen and even then you&#x27;ll still need some device that will modulate the light so instead of a dedicated light bulb you&#x27;ll have a dedicated lamp.<p>Considering the engineering limitations and the cost involved having normal light bulbs that can connect to your network via either WiFi or well via basically &quot;DSL&quot; via sending a phase modulated signal over the AC wiring in your house similar to how those power plug Ethernet &#x2F; WiFi extenders work.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Power-line_communication" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Power-line_communication</a><p>Again this is a very kickstarter &#x2F; TED talk worthy idea that sounds brilliant but it will probably go the way of the GyroJet because it&#x27;s just so dumb on so many levels.
