[LINK] Has the world just gone light-headed, or completely bonkers?

[Kim Holburn]

From your wikipedia link:

In an ordinary LED light globe, the LED itself is silicon and the bulb has power circuitry in the base that includes silicon circuitry.  Perhaps you mean something different by "active"?  

The smart light must have a microprocessor, volatile memory, networking, clocks and perhaps one or more kinds of radio and switching.  That's a lot more transistors.
