I have done exactly this with WS2812 addressable strips. If you do this some things to consider:

  • I used QLC+ output via wifi/wire to ArtNet -> Strip controllers which then drive WS2812 strips. Make sure to hard address the controller(s) .. AND attach 5v power to the STRIP .. you can easily blow the 5v output the converter plugs on these pulling too much amperage.. but if you do the "signal" side will still work. Also, a single "channel" will xmit more than 1 Universe. So output 1 can do U1-1:512, U2:1-512 ..etc. Given your count you might get the higher density version
  • you're gonna want GOOD power supplies to the strips.. and i'd recommend tapping the strip(s) top, bottom and in the middle with +5 and GND as needed to get enough power.
  • I recommend soldering all connections.. the presson connectors you can buy dont' work consistently .. but are a good basis for soldering.
  • You're gonna wanna be careful how many universes you use for this project, considering each LED uses 4 addresses GRBW.. 128 LEDS makes for 1U. If you go more than 5 or 6 Universes.. you should consider Gig Ethernet.
  • 1 6 foot of strip is ~300 LEDS .. so 10 of them is 3000 LEDs * 4 Channels each .. you're gonna use up alot of address space ;)

    Can PM me here if you want more info ;)

The cheaper/home brewish solution is to to put a large psu and the pixel controller together on some mounting board and put a 25ft tail on your pixel bar and run It back to the controller/psu
Good option when the budget is low
The green connectors you see on a lot of controllers will unplug from the controller to make transport of the bars easy
If you don’t mind dealing direct with China star times led is a great resource for everything led strip otherwise a lot of there products are marked up +200% and resold all over ammazon under other brands

Side note pixel protocol used post controller usually stars to get buggy after about 35ft of cable to strip


What you are describing in your post is the expensive/plug and go solution I used in a project recently due to cable run lengths of +100’ was the entech pixelator system .
the controller had to be integrated at the strip for the signal to make it all the way to the end of the cable
Worked like a charm for 150 5m bars in a room with 117ft to the roof

Hope that helps
