Fancy side light LED strips are a great alternative for folks who have loved and used NeoPixel strips for a few years but want gorgeous, glowy light emitting at 120 degrees.
We already have flexible LEDs, so these bars are more on the rigid/firm spectrum of LED strips. They're made on a single long FR4 PCB, so they've got some mechanical stability, you can run them along a thin edge. They look fantastic as accent lighting, back lighting, edge lighting, etc! Note that the FR4 is rigid but requires support so it doesn't droop and crack. It's not intended to be bent or curved at all, and if you do so you may crack the copper traces.
This LED Bar is half a meter long (50cm / ~19.5") with 120 LED/meter pitch, and features 60 addressable NeoPixel LEDs. You can use any 'NeoPixel' compatible library or microcontroller to drive these LEDs just like you expect.
These bars come with a 3-pin JST SM connector on both ends, you can remove these easily with a soldering iron.
