im making a ridiculous led light. its powered by 125vac being rectified to 175vdc across 6 100 watt led cobs in series with 3 rows of 6 in parallel. i need a way to deplete the capacitors when i turn the light off because while the cobs can drain the capacitors down to like 100 volts, after that it drops below their forward current and does not drain the caps anymore and i dont want all of that power being stored for no reason. i need a good way to slowly drain the caps when the power is shut off that doesnt interfere with the lights while its on nor involves a snap discharge or anything like that, i want to actually make this into a usable light on a stand so i want to avoid having a loud explosion every time i turn the light off.
