MaryB, thank you very much for explaining how the LED's consumption is figured, including the fans and heat waste.
Let me explain my problems with electronics and milliamps.
I was involved most of my life with 120-240V at up to 60Amp usage. Home and light commercial wiring/troubleshooting, AND, a lineman for a New Jersey Power Co, at up to 7200/12,500 V, live handling. Making those kinds of systems do what was needed, was no problem.
To put that in electronic mode, I'm a welder, not a solderer. Used to be, didn't matter what the current draw was in a specific application.
Now, trying to save every tiny bit of energy because of high power company rates (30 cents Kwh here) and constant outages, (2 since I started typing this response) fridge compressor is twisting in it's frame, trying to restart-restart-restart, etc. UPS on the computer beeping, and, if turned on, TV cutting out, restarting, as many as 3-4-5 times in just a few seconds, span, is why I am about to hook up an off grid wiring system in my house.
I do have a few LED strip lights made up, by wrapping a section around a white plastic bottle, that I have soldered a standard screw in light bulb or screw in Fluorescent bulb base, and screwed them into flat base light sockets for ceiling lights or pigtail sockets for temp lighting, especially over my computer desk.
Too much hijacking on this thread. I will start my change over thread in a few days.
Thank you again, MaryB.
