- Contents: This set includes 10 high-performance green conventional LEDs, each with a diameter of 3 mm. Each LED features connection cables and a built-in resistor, designed for a 5 V power supply. Ideal for various applications, such as model making, speedometer illumination, and TV backlighting. - Size & Compatibility: Each LED has a compact size of 3 mm and comes with approximately 20 cm of cable, making them versatile for numerous projects. Their small footprint allows for easy integration into tight spaces without sacrificing performance. - Light Intensity: These LEDs emit a brightness range of 8000 - 15000 mcd, ensuring vibrant illumination. They are dimmable and operate efficiently within 4 - 6 V, with 5 V being the recommended voltage for optimal performance at a power consumption of 20 mA. - Specifications: The LEDs feature a 30° beam angle for focused light emission. A notch on the negative pole prevents damage from reverse polarity; if connected incorrectly, the LEDs will not light up but remain intact. The LEDs can be easily soldered or clamped to the cables for secure connections. - Practical Applications: 1. Model Making: Enhance your scale models with realistic lighting effects to bring them to life. 2. Speedometer Lighting: Use these LEDs to illuminate gauge clusters, providing clear visibility and a modern touch. 3. TV Backlight: Create an immersive viewing experience by adding ambient lighting behind your television. These LEDs offer reliable performance and flexibility, making them a smart choice for hobbyists and professionals alike.
