Re: Have they finally solved strobing?
LEDs don't run on voltage - they run on current. I wish I had a whiteboard and ten minutes to explain.
But you need a driver between the (fluctuating) voltage source and the LED that wants a constant current. The design of the driver has everything to do with the flicker. One can design a nice smooth constant current driver, but it will probably use a more expensive storage inductor. Or, you can use a resistor and string a lot of LEDs in series, which will only conduct on the voltage peaks, creating a power mains frequency flicker. That is a lot cheaper, but runs a lot of peak current through your LEDs. Also, the current regulation vs. voltage input is not good.
Yes, incandescents were easier to shop for. Don't get me started on reliability claims.
