Powered by 360 Fashion Network, the thin 3MM white illuminated LED ribbon uses 2 thin conductive threads to light up in 4 distinct modes: all on, fast blink, slow blink, and slow fade in & out. A tiny grey removable controller snaps onto the end and uses 2 x CR1220 watch batteries to run for hours continuously. Cut the ribbon to the desired length and watch your project sparkle and shine!
