A friend wanted to replace his landscape bulbs with LEDs, the flicker was horrible.
We added a bridge rectifier and the 120 hz flicker was less offensive.
So, we added a capacitor, the flicker was gone and the LEDs were much brighter.
I noticed they were also becoming warm so I measured the voltage which was now over 18vdc.
I suddenly recalled that a load resistor was always added when I used to make linear power supplies, a few years ago.
Can't remember the formula I used to use but google found a nice article about this:
