Granted my father was older than I am when he had his done, but when they did it the first time, they fractured his femur, and had to go back in and do it again. In the meantime, he needed bypass surgery. So in a six week period he had three major surgeries. As a result of the surgeries, he was left with "scanning speech". He speaks slowly, and has to THINK for his next words in a sentence. He often doesn't get the word that he wants. That's what scares me.Anesthesia is way better than it used to be. Talk to an anesthesiologist if you're concerned about it. I'm sure they will allay your fears.
Thanks for your good wishes.Poppy, I know any type of surgery stinks. I recently had to see a neurologist for a second EMG to find out the extent of nerve damage causing neuropathy, hand tremors, muscle twitches, and myoclonic jerks (among other things). The procedure involves being zapped with electricity several times and then stabbed with a bunch of needles. Then the doctor took over for the nurse and did it all over again. No anesthesia, and the test came back normal. So remember that going under anesthesia may be scary, but some procedures are literally torture and done without it. I hope all goes well with your surgery.
Nice! Goodbye 60hz flicker. This will make it subtly more conducive to reading, as well as saving on replacement costs.Headed out to the garage to fire-up the BBQ for our New Year's Eve dinner.

But first I needed to season the new Grill Grates.

Watched a video that advised rubbing new grills with an onion after bringing the BBQ up to about 500 degrees. It was 22 degrees outside, so it took a while.

Was about two beers in ...... when I ran out of propane. Rookie Move! I had to bring them into the house to finish cooking.
New Year's resolution - To not run out of propane in 2022.
In my defense, if there really is one, I spent most of the day at our school's library replacing the original T-12 fluorescent tubes with LEDs. Took most of the day because the ballasts had to be removed and the fixtures rewired.

Before & after picture. ^
LOL! I can hear him. Once, teenage years, I washed my mom's cast iron skillet. She was not a happy cooker.One year I borrowed my oldest brothers charcoal grill and when done I cleaned it up really nice.
I believe that was the maddest he ever got at me. I said "but look, it's all shiney and new looking"……
"You removed all the flavor you idiot" he said.
And no more HMMMMM. One of the fixtures had developed a nasty buzzing, and the LEDs require less than 50% of the formally used electricity. Win, win, win.Nice! Goodbye 60hz flicker. This will make it subtly more conducive to reading, as well as saving on replacement costs.
It seems that every library I've ever been in has that ONE bad ballast.And no more HMMMMM. One of the fixtures had developed a nasty buzzing, and the LEDs require less than 50% of the formally used electricity. Win, win, win.
Probably much more conducive to reading, especially if those were old-school halophosphor T12s with CRI in the 60s. The improvement going to LED is dramatic, even when you used decent fluorescent tubes before. In my workroom I was using CRI 90 5000K tubes on an electronic ballast. No discernable flicker, and I was happy with the color rendering. Then I bought CRI 93, 5000K LED tubes. Rewired the fixtures, removed the ballasts. Enough of an improvement to not only notice, but to blow me out of the water. CRI numbers are somewhat deceptive. Fluorescent tubes have lots of spikes and gaps in their spectra, even the high CRI tubes. They simply adjust them to game the CRI metric in their favor. LEDs have a continuous spectrum, even if there are some peaks and valleys. End result is even under the same CRI, things look MUCH better with LED lighting.Nice! Goodbye 60hz flicker.

A CRI of 99?!! Wow. I need to look into these.Probably much more conducive to reading, especially if those were old-school halophosphor T12s with CRI in the 60s.

I bought some boards from Cutter last year with Nichia Optisolis (CRI 99) and Cree Fidelity (CRI 98). Both are pretty much like artificial sunlight. Other than the lack of UV which might make some things fluoresce, impossible to tell the difference.
Oh yes, quite a difference. And the new lights really make the colors on the book covers pop!I finished the last six today. My thumbs hurt from all the wire nut twisting, so I'm having a beer.
Here's a picture of the last three to go. I turned down the exposure on the phone and the difference really shows. I don't know what the CRI is for the LED, but they are 5000k.
BIG difference!

Most electricians use Wagos instead of wire nuts on fluorescent fixtures for that reason. At least use an Ideal twist a nut screwdriver with the wire nut twister to make things easier.I finished the last six today. My thumbs hurt from all the wire nut twisting, so I'm having a beer.
I was L@@King at A's selection of lever nuts this very morning. I have two more large fluorescent / LED swap projects at church, so was giving them a look. I also purchased some Kline automatic wire stripper pliers. Figured it was time to work smarter than harder.Most electricians use Wagos instead of wire nuts on fluorescent fixtures for that reason.
