Does it exist - 4ft LED fixture dimmable via wall switch

Looking to do 6 total 4ft LED fixtures in my garage to replace my two incandescents (two runs of 3 fixtures).

I'd like to screw a plug adapter into the existing bulb bases, then run the LED fixtures off that (if I have to, I can yank the bulb bases all together to grab a ground.

The caveat - I'd like to be able to set brightness from the existing wall switch (LED compatible dimmer switch).

Does such a thing exist? So far everything I've seen requires new wire for a 0-10v knob. I don't have access through the ceiling or wall to run such a switch. I'm limited to the existing wiring.

I could do something alexa / google home enabled for dimming at the fixture if necessary.

Any suggestions or thoughts?

Existing incandescent (x2):

Tried upgrading them with supposed 8000 lumen LED units. No way they're that bright. And they're pretty directional, casting shadows all over the place. They're getting returned.

Should be possible as I have led wafer lights in my bathroom that are dimmable plus lots of screw in bulbs are as well.

I have the same need, but for 2ft fixtures

Absent any data to the contrary on their website, I would assume that fixture uses 0-10VDC dimming, not the triac line voltage dimming the OP needs.

That is kind of a negative thought, my mind tends to work that way also. But in the case of 0-10 dimming I tend to disagree, as the 0-10 stuff seems to be labeled clearly.

I have been surprised after testing LEDs labeled as non dimmable and both times the fixtures did dim using a LED rated dimmer. Getting the LED to start off of the dimmed voltages can be a trick. You need to find the hidden adjustment that limits the dimmers range.

str8shot - One $30 receiver per fixture? + DC power supply $? Sounds expensive. If you want dimming that bad I'd find a way to gracefully run 2 18ga stranded wires from fixture to fixture to dimmer. There's no code or fire hazard to deal with. You could even staple the wires to the ceiling and paint them white. Or find some really small "U" trim to hide them.

Looks like I found a possible solution. Just do standard 0-10v fixtures, and buy these components:

RF, battery operated single gang rotary dial -

RF receiver - 0-10v out -

And you can pair multiple receivers to a switch, and vice versa. No new wiring required.

That would eliminate running wire anyway.

Wireless fixture controls are a legit solution to many lighting obstacles (although this one is ebay/amazon grade). #1 objection that installers have to dimming is that they cant run the control wires. Therefore, wireless controls are the solution. If the controls are too expensive (as these are), then the fixtures will get installed with no controls. Until the control solutions come down in price and are more reliable, the fixtures will continue to be installed without controls.

Since three fixtures will **** up to one another in a long row, I can use one receiver per row (2 receivers total) by running wire to each fixture internally. I wouldn't buy a receiver per fixture.

AC/DC power supplies are cheap. I actually have a few laying around.

I was going to forgo the ready built wireless solution and build one myself using ESP8266 modules (~$5 each, integrated wifi, etc), but I like that knob.

Much easier than opening an app or web page to change brightness, and much more wife friendly.

I'd be looking at ~$90 bucks total for the dimming gear. Not terrible.

I'll have to measure spacing between the current light fixtures, but I could do a "U" shape with a few more fixtures and have them meet each other. That would eliminate one receiver. I just think it might look wonky.
