- Contents: This pack includes 10 high-performance yellow conventional LEDs with a 5 mm diameter. Each LED is equipped with connection cables and a built-in resistor, making them compatible with 24 V applications. - Versatile Size: The LEDs feature a compact 5 mm size and a cable length of approximately 20 cm, allowing for easy integration into various projects, from model making to lighting applications. - Brightness and Dimming: With a luminosity ranging from 3000 to 5000 mcd, these LEDs provide a strong light output. They are dimmable and designed to operate between 20 to 28 V, with 24 V being recommended for optimal performance at a power consumption of 20 mA. - Practical Specifications: The beam angle of the LEDs is 45°. The negative pole is notched to prevent damage from reverse polarity; the LEDs will not light up but remain intact. You can easily solder or clamp the LEDs to cables for flexible use. - Applications: Ideal for enhancing model displays, illuminating speedometers, setting up TV backlighting, or any project requiring efficient and reliable lighting. These LEDs are a practical choice for hobbyists and professionals alike.
