    Strings of sixty white LEDs in series will take about 180 Volts. What has to be considered on connecting them directly to 120VAC/180V peak ? No resistor, no capacitor, no rectification.
    Two strings in counterparallel, conservatively driven for Vf =3, thus under its rated recommended current aiming for longevity.
    Thermal, spikes, failures, safety...
