The Battery COB LED Strip Lights are a great choice for those who need a reliable and efficient lighting solution. The working voltage is DC3V, which means it can be powered by batteries, making them an ideal choice for projects where a power source is not readily available. The width is only 4mm and can be widely used for lighting decoration in an ultra-narrow space, sand tables, toys, DIY projects, DIY cars, etc. It can be cut to any length for your project from the copper welding point and reconnected with wires or COB Connectors, and the minimum cutting length is 12.5mm. High-Density COB 12V LED Strips use the newest chip-on-board technology, 480PCS LED Chips per meter, flexible and bendable. Brighter than the SMD LED Strips, no visible light dots and dark areas, uniform light emission, and a beam angle up to 180°. The color rendering index is over 90Ra for quality color rendering. Only IP20 non-waterproof products are available and recommended for indoor applications. The back has double-sided adhesive tape, making it easy to mount them where you want to install them. It can connect to a Light Dimmer to adjust the brightness for various scenes.
