Default LED shop lights retrofit from Fluorescent lights

I have some 4 bulb T8 fluorescent fixtures in my shop, 10 in total, and 3 decided to go out. I was fairly sure it was the ballast, and so figured now was a good time to try some LED bulbs.
I didn't want the ones that still use the ballast, as what would be the point in that??
I found these direct wire LED bulbs from Menards, and so I did some wiring work on just those 3 fixtures to eliminate the ballast and installed the new LED bulbs.
Each bulb is rated for 2200 lumens, so with 4 in each fixture that gets me 8800 lumens per fixture.
With 16ft ceilings, this was definitely an improvement over the fluorescent bulbs!
Now only 7 more to do... which I'll do once those other ballasts decide to fail.
Here's a video I put together showing it all: Watch until to the end to see the comparison of before and after!

The best thing I did in my home was switching from flourescent bulbs to led bulbs. Much more light, much more life, and much more less power draw which means a lower electricity bill.

I did the same thing, deleted the ballasts, reused the old fixtures.

I used these:

Best lighting move I have ever made!!!

I used the single ended powered led tubes from Sunco which is also listed on ebay. A very simple installation.

If Leviton lamp holders are used there is a big issue with connecting line voltage directly to them, see this from Leviton: https://www.leviton.com/sites/REST/c...10-02-0J-W.pdf

I have yet to see a money saving ROI that was not based on 24/7 on time
More light, maybe
but my 6 old style, free, 3 x 4 foot fixtures give me enough light to do brain surgery.
They are on less than 8 hours a day

I'm not debating your concern or the info in the linked document. And I will concur that some wiring going to the "tombstones" may be thinner gauge and probably not rated for full wattage at line voltage.

That said, I would venture that connecting a 19w LED bulb to a fixture that once had 600v start voltage going to a 32w or 40w bulb would probably not pose any hazards, ever. I don't have any specific specs but thought this LINK was enlightening...
