This came from a YouTube tear-down and well documented. His only error was measuring AC current with a DVM that internally uses P-P converted to RMS wit the internal assumption of a Sine wave ( common measurement error)
He adds a tiny diode to the PIR to make it retriggerable by motion to extend time and prevent cycling.
IF you compute the RC products, you can understand as I do how the energy is stored with 25T and low ripple using 15 ohms ESR per LED.
I like this design, but would like a faster response time than is possible with a passive PIR.
