Maximum in e14 body of this size is 4.4w
In E27 body is 5w
With 6w COB LED
It is the same model of led driver inside for all 3-6w models, but different input (400v) capacitors.
Sample models is 95-285v. If model marked 220v, it is with reusable fuse and 1.5-350CA supressor.
In this sample I placed wrong resistor for 5w (2.4ohm), it must be 2R2 for 5.0w (for hot bulb)
