Power factor correction and THD

Reading through the article I learned that the power factor correction offered by the new chip is 98% and Total Harmonic Distortion (THD) is less that 18%, which seems good. How are these parameters for the conventional LED driver circuit? Apart from the improvement in reduced flicker and compactness without larger components - inductors and capacitors would give this an advantage over the conventional LED drivers.

"The IC EL01 rectifies the 230 VAC mains voltage and feeds it to an AC direct driver without the need for smoothing."

Is this correct or should it be DC?

Lower BOM cost

With fewer components, the logistic is easiler to handle and I suppose the BOM cost can be lower provided that the cost of the IC is not higher than the cost of alternative solution.

New IC for Driverless LEDs

I'm assuming that the technology can easily be modified for domestic US applications using 120 volt AC power (and our slightly higher frequency can only further reduce flicker). This is a great advance since the bulk of electronics currently required for running off the mains makes the packaging, the cost, and heat dissipation significant issues for household replacement light bulbs.

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
