This affordable and high-powered 1W COB light strip is perfect for hobby projects. The strip itself measures 30mm by 5mm but thanks to super-charged COB LED technology, this little chip emits an impressively bright light. Operating voltage is 3V. It comes with 4 inch (10cm) long black and red wire leads already soldered for easy connection to your circuit. Use it with 1, 2 or 4 AA batteries in series (see battery holders below in related products) or with a solar cell.
