Just changed the tubes for me. I didn't even need to replace/remove the ballast.

I did my whole shop about 3 years ago. I paid a company to do it, it was a ton of money, but they structured it so that the amount you saved on your electric bill , was your payment every month . Basically free to me.
I used to have 6 8x2 footers, and at least 20 4x4 footers . They were all old and ugly too !
Cut my bill in half, and my shop is 4 x brighter . I have not had one burn out yet. In the past, about twice a year, I had to go purchase a case of bulbs, and get the big ladder out and replace 10 or so bulbs, and the occasional ballast .
And, yes, just wire them straight to 120v, cut the ballast out of the equation .

My natural tendency to be cheap and lazy led to an install of halogen work lights - about 6-8 of them scattered around up high (my natural tendency to be cheap and lazy means I ain't gonna run out and count).

as they bulbs burn out, I'll stick LEDs in there

You just remove the ballasts from the circuit. The bulbs I bought at Menards had complete instructions. I think I had to swap some wires so it was positive on one end and negative on the other. It was simple to do though.

Right, there are LED's that can be installed without wiring around the ballast. My concern was that if the ballast went bad I'd be in the same position I was with the fluorescent bulbs, flickering and no lighting.

FYI: another DIY video that might help.....



It just dawned on me I have fluorescent fixtures in my living room that I hardly use - they are behind curtain valences up high above my picture window and patio door. They have always been stubborn to use. This conversion would be a fantastic upgrade for them. Woot!

I have to revise my last comment about the lights in my living room. After looking at them while lit - it's obvious they are meant to give an effect of light bouncing off both the ceiling and wall and with the LED's only sending light in one direction I don't think I'd have the same effect. I guess this is what is considered indirect lighting. Maybe they would but probably not to the same extent. Will have to give more thought.

Here's what I was talking about.

Looks pretty cool with the indirect lighting.

BTW....on this side of the room I have a both a warm white and a cool white bulb. Just turned out that way. The other side has both cool. For this application (my living room), I prefer the warm white. For the garage it would be the cool white.

Transformers (ballasts) are very lossy (inefficient)

The whole reason to move to LED is efficiency.

Seems crazy to not bypass the ballast and us 120v LEDs

I love it when the DIY guy is missing part of a finger.
Clearly, he has real world experience.

Installed a 5000 Lumen screw in to replace the main light in the garage. What a difference! I am afraid to look directly at it as I wish to retain my vision
When it warms a bit, I will move the 911 outside, gain access to my 2 4" fixtures and replace the fluorescent tubes with LED's.

Very useful thread and timely as WERK I had just sent me a photo of his car bathed in blinding light and it had caught my interest.

I'm in the process of installing 16 4' single tube LED fixtures I bought on Amazon, 8 per pack for under $60.00 per pack. I have 6 up and my wife said it looks like a surgery suite. It seemed all my fluorescent bulbs started to fail at once so the time to do this was right.

I also have the interior of the garage (walls and ceiling) painted in bright white gloss latex enamel. It is reflective and cleans great!

Pics to follow as soon as I'm finished installing.

I ordered a couple of these, https://www.amazon.com/gp/product/B07XB7L2JY/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1. I like the shape of the lighting area and the downward light, should be no holes.

So I have 110 fixtures / dual 8' tubes with dual pin contacts. Home Depot did not have this style in stock. Looks like I'll need to go online.

8' tubes in LED will often be too flexible and sag in the middle. get out the craft wire. ..

Ballast Bypass (=bypass ballast and wire directly to the tombstones on the end)

Make sure you read the box.

I got both kinds and I'm returning both:
1. Feit 24" direct replacement.
The store didn't carry any warm white LED fixtures which are direct-wire.
It was a nice warm light, but there is still vibration on the bulb and buzzing from the old ballast.
Bulb was $10. New ballast would be $10-30 and probably hum also.
Might as well buy an entirly new LED fixture.

2. Feit 4' ballast bypass.
These have wires attached to the bulbs instead, and flimsy plastic push connectors which are 1-use.
Once it's rewired..only Feit replacement bulbs will work in the future.
A sneaky little proprietary hardware trick.

Okay, I'm now under conclusion that the Feit brand is garbage.

Instead of their ballast bypass with funky proprietary attachment...I tried their direct replacement for the kitchen overhead.
They blinked and went out. Both ways.
The ballast runs the normal florescent bulbs fine.

And I just remembered the same thing happened many years ago with shop lights when the LED thing was new.

Strike three trip back to the store.
Again. Sigh.
