Dimmable LED puzzle

Could use some help, I've done tons of combing through this forum and various options for the new garage. 600 sqft 3 car, wanting over 20k lumens dimmable for when the golf emulator goes in. Also, total wattage for LED needs to be under 150, which is where I'm getting stuck. I've got smarthome automation with to link Kasa switches and that's all their dimmer can handle. I already rerouted the switches for the garage in the house and would prefer to keep it that way as well . Any suggestions? Having a hard time finding any dimmable T8 LEDs that put out any respectable lumens.

You're going to need multiple dimmer switches in parallel. That should be easy enough to program with a "scene".

0-10VDC dimming requires 0 Watts. Skip T8 retrofit bulbs in favor of discrete LED fixtures which usually come standard with 0-10VDC dimming option. You have to run 2 leads (violet and grey) from fixture drivers to a single (or multiple if you prefer) dimmer control.

Your goal shouldn't be 20K lumens, it should be footcandles at workplane.

Type of fixture used depends on ceiling height and fc target.

and make sure all the dimmer wires are phase the same i.e. all "grays" to same point and all yellow to same connection. If you do it haphazardly the dimmers will act strange ( if at all)

I have a very specific dimmer to use and it's not 0-10v

Likely much cheaper to source an appropriate dimmer for typical 0-10VDC dimming fixtures. Selecting fixtures based on an existing dimmer is backwards, though I'm sure suitable fixtures can be found for a price.

I understand this, but it's a 'smart' dimmer to utilize home automation functionality. The dimmer is the starting point in this instance.

The Kasa dimmer switch will only contol "dimmable" LED bulbs via line voltage. There are dimmable T8 LED bulbs, but mostly they require a dimming ballast or driver. The ballast or driver will most likely be 0-10VDC, not line voltage. Philips makes a 13w dimmable LED tube (#473934) that works with their line voltage dimming ballast REZ2S32SC. http://images.philips.com/is/content/PhilipsConsumer/PDFDownloads/United%20States/ODLI20180301_001-UPD-en_US-PLt-16118CR_InstantFit_Ballast-Compatibility-Guide_2018-1.pdf You would definitely need to verify compatibility with your Kasa dimmer.
Anymore, there are very few LED fixtures that are controllable via line voltage dimming. An exception might be a wafer light or other downlights. Liteline Luna series is one example. These require a Triac dimmer.
As said above, finding a fixture to match your dimmer is doing it backwards. I suspect that contacting Kasa would be your best bet. They should know of products that are known to work with their products.
Good luck,

Extremely helpful. I actually bought 8 of the 473958 with two four bulb fixtures to test it out with a non dimming ballast and it was a no go. I missed that they have a line voltage dimming ballast. I'll have to buy one to test it out before I buy four of these suckers.

Bought 4 of the REZ2S32SC off eBay for about $80. Need to pickup some non shunted sockets at Lowe's tomorrow. Crossing my fingers that this works.

If you are power limited on dimming, why not just have different switched circuits that bring on a fraction of the total lighting.
