This light has a swirling yellow and blue resin shot glass base with a single RGB color changing LED bulb and about 14 strands of 1.5mm side glow fiber optic cable. As the colors change, you may see 2 different colors at the same time! The fiber optic strands form a little fountain of light Side glow fiber optic cable allows light to pass through the sides of the cable, and the curved strands create additional light points. The small size makes it ideal for a bedside table or desktop. So how does a single 3mm LED bulb give multiple colors at the same time? The bulb has 3 tiny diodes encased in an acrylic shell. The diodes are red, green, and blue (RGB), which are the primary colors in light. The colors change by the 3 diodes fading on and off, which creates many different colors. Since the fiber optic strands rest directly on the bulb, they may pick up light from more than one diode at a time. The light has a 3m (almost 10 feet) USB cord and comes with a USB / AC adapter. The light uses a fraction of the electricity of a standard 4W night light. It's really cute as a desktop light too. The shot glass measures 1 3/4" in diameter and about 2" tall. The fiber optic cable top is about 5" tall and about 7" wide. Need a customized color scheme? Contact me about options and lead times. Usually, it takes me about 1 week to make special order lights.
