Re the reliability factor or lack thereof of LED bulbs.
“Don’t they have to down convert the 120VAC line voltages to a polarized low ~ 1VDC? Of course, they probably stack the LEDs in parallel (or series like your Christmas tree lights)”
No, the reliability has been increased multiple orders of magnitude by using the pre recombining DC phase modulator to reduce the inherent weakness in the post stasis field during activation of the initial second phase circuit by pass.
You have to get DC out of AC somehow. They do it fairly cheaply with power adapters for cell phones and such. But it is still an inherent reliability problem. And cheap usually means less reliability.
The power adapter for my routers fail fairly frequently. More than they should. They do run 24 hrs a day. BTW, if your gizmo stops working always look at the AC power adapter as the culprit.
The simple filament solution is well, simple. And simple means reliable. I wonder if for the same price as an LED bulb, you could make a filament bulb (incandescent) as reliable or more reliable. Anyway, incandescent bulbs are designed to be cheap-throwaway and with an expected failure rate.
