Hello,
Is this so?
("direct drive led" means the leds are connected direct to rectified mains with no switch mode driver used...instead some special switchs are used to simply switch in (and then out) more leds as the mains half sine rises and falls at 100Hz)
The below article says that "centralised" direct led drive is less efficient than using a switch mode driver, but does not state efficiency for the "distributed" direct drive led approach.
