Hi, folks.
I bought a pre-lit LED tree on clearance last year right after Christmas. The tree looks great except for the fact that the LEDs flicker. It's my understanding that this is caused by the unrectified AC voltage so that the LEDs are running at a 50% duty cycle at 60Hz.
My question is, can I just build a bridge rectifier to provide DC current to the lights? It sounds simple enough but I know there are big differences between AC and DC and I'm not sure how this change would affect the LEDs. I don't have specifics on the LEDs other than that they appear to be the same, standard mini bulbs that all Christmas light strands use, including the flicker-free ones. If more info is necessary I do have a scope and most other common test equipment.
