This 5 mm LED Diode Assortment Kit offers versatile lighting solutions with 100 high-brightness LEDs across 10 distinct colors, including white, red, green, blue, yellow, orange, UV, and warm white. Each color corresponds to precise wavelengths (e.g., red: 620 –625 nm, blue: 455 –465 nm) and varying luminous intensities, such as warm white (14 ,000 –16 ,000 mcd) and green (15 ,000 –18 ,000 mcd). Designed for low-power operation (DC 3.2 –3.3 V, 20 mA), these LEDs are energy-efficient and generate minimal heat, ensuring safe handling and prolonged use. The round clear lens provides a wide 120 ° viewing angle, ideal for uniform light dispersion. Compatible with Arduino, Raspberry Pi, and breadboards, they suit DIY electronics, PCB circuits, and science experiments. The through-hole DIP 2 -pin design simplifies installation, while the 100 -piece mixed-color kit (10 colors × 10 pcs) supports creative projects like colorful throwies or indicator lights. With stable performance and compact 5 mm size, they are perfect for space-constrained applications, from hobbyist prototypes to industrial replacements.
