There are lots of LED tube lighting on the market nowadays, but that which makes the NeoPixel RGB mild strip so nifty is the translucent silicone rubber outside, which acts as a light diffuser. The end result is light rather than dots that are ugly. The strip is filled with 20 each of green, red, and blue LEDs, each clustered together to produce a variety of colors. Each strip measures 1-meter extended and needs a 9v into 12v power source, together with NeoPixel WS281x information to tell the LEDs what colour and brightness to display.
Love the look of neon lighting, but don’t wish to manage the fragility of glass and higher voltage transformers? This bright, flexible lighting can be bent into almost any form you want without risk of harm, and also a lights up in almost any color also.
