You won't believe the output on this flashing color mixing brilliant LED. Operates from a 3.5VDC and has a water clear lens. When power is applied it flashes each color; red, blue and green for several seconds, then it slowly mixes and fades the colors together to form other colors. Beautiful, brilliant and awesome. Long leads - factory prime. Use a 100 Ω resistor in series with a 9V battery if you desire to use it at a higher voltage. Sold as package of 5.
