What do you call RGB Addressable LEDs without RGB? Like, all WHITE LEDs instead? You'd call it the StripStar!
Sometimes you don't want to add color; just illumination. For those times, here's an interesting addressable Stripxel - the StripStar!
144 LEDs/M, with each pixel having 3 white elements. Using standard 3-channel (usually R/G/B) control at 8 bits each, this cool-white LED strip offers 24-bit illumination control. That's 16,777,216 (16 million) levels of brightness control out of each pixel on the strip.
So where 255 levels of brightness through 3 colors gives you great color selection, it isn't great illumination control. This strip allows you to pack a very dense, accurately controlled illumination strip into a project that lets you feature incredibly smooth, fast effects.
Note: Photos taken at 1/4 brightness. Brighter blows out the camera imager!
