With a \u003cstrong\u003ediffused lens\u003c\/strong\u003e that scatters light evenly across a wide viewing angle, this LED is visible from virtually any direction — making it the preferred choice for status indicators, power-on lights, and any application where omnidirectional visibility is important.\u003c\/p\u003e\u003cp\u003eBlue LEDs have a higher forward voltage than red, yellow, and green LEDs (typically 3.0–3.4V), making them ideal for 3.3V and 5V Arduino circuits with a current-limiting resistor. The 5mm through-hole package is breadboard-compatible and fits standard PCB LED footprints.
