【 Warm White LEDs】 These prewired LED units feature warm white light emitting diodes, a perfect fit for models and tight spaces. The LEDs are made with meticulous attention to detail, offering excellent brightness and color consistency. 【Convenient and Easy to Use】 Soldering LEDs can be challenging, but these prewired units eliminate the need for complex soldering work. With a wire length of approximately 200mm, connecting the LEDs is hassle-free. The cathode wire is 10mm shorter than the anode wire, allowing for easy identification. 【Compact and 】 Measuring at just 04x0.02x0.016 inches, these 0402 LEDs are incredibly small and perfect for various applications. The LED units are designed to be space-saving, offering flexibility and convenience when implementing LED lighting solutions. 【Resistor for Convenience】 Each LED unit comes pre-soldered with a resistor for a 12V (20mA) setup, providing added convenience for users. If you prefer to use a 3V setup, you can remove the resistor without any hassle.
