Whats the deal with these then?, never heard of a driverless LED?

Ideal Kev then in future they can pay any wanker £3 an hour because there will be no skill left in our job no fault finding no lamp/ballast/ignitor recognition no reconfiguration of wiring just bin the old led fitting and connect one poxy flex up

I know with normal LEDs if you connect enough of them in series, you can run them right off mains without a driver or resistor or capacitors...(just add a diode-bridge to reduce flicker - 60hz/full-wave instead of 30hz/half-wave)

I think that's all they are these days. Even in the filament lamps the PCB is in the base so can't have much going on in there.

A lot of these have a control chip which switches the leds in different series/parallel combinations on the fly as the (rectified but not smoothed) mains waveform goes up and down. Clever? Well yes, unless you object to the annoying 100Hz flicker and the fact they regularly pop on mains transients!
