Another requested test. Putting a 10uF 400V capacitor across the LED array on the driverless 20W LED. This required a little silicone surgery to gain access to a concealed track.
The result was actually quite good, and got rid of the real harshness of the flicker.
If you try this then it's probably a good idea to use a couple of wires to jumper from the two connection points to a cooler area for the capacitor. I'd also suggest putting a 1 Megohm discharge resistor across the cap to avoid nasty surprises. I used a 10uF 400V electrolytic capacitor and added a 10 ohm resistor in series to limit the peak current as the capacitor charges at initial power-up.
