This affordable and high-powered 3W COB light chip is perfect for hobby projects. The chip itself measures 20mm in diameter but thanks to super-charged COB LED technology, this little chip emits an impressively bright light. Operating voltage is 9-12V. It comes with 4 inch (10cm) long black and red wire leads already soldered for easy connection to your circuit. Use it with a 9V battery (see battery holders below in related products) or with a solar cell.
