Product Description The 5mm Red Diffused LED is the universal standard for "Stop," "Power," or "Error" indicators in electronic circuits. Featuring a red-tinted frosted lens, this LED provides a soft, wide-angle glow that is easily identifiable from multiple angles without being blinding. Unlike "water-clear" LEDs that act like tiny spotlights, the diffused casing ensures the entire dome illuminates evenly. These LEDs are an essential component for any hobbyist or engineer building control panels, alarm systems, or status beacons for robotic projects.

Key Features

Soft Red Diffusion: Frosted lens eliminates glare and provides a uniform, professional status glow.
Instant Function Recognition: The tinted red lens allows for easy identification even when the device is powered off.
Standard 5mm Profile: Perfectly compatible with breadboards, perf-boards, and standard 5mm LED mounting clips.
Vibrant Signal Hue: Delivers a classic high-visibility red light that is the industry standard for "Power ON" or "Fault."
High Efficiency: Low forward voltage requirements make it ideal for long-term battery-operated signaling.

Technical Details

Anode (+): Longer Lead
Cathode (-): Shorter Lead (Indicated by a flat edge on the LED base)
Wavelength: 620nm – 630nm
Operating Temperature: -25°C to +85°C
Soldering Temp: 260°C for less than 5 seconds

Prototyping and Engineering Tips from Robogears

Indicator Logic: Red LEDs have the lowest forward voltage requirements (1.8V – 2.0V). When powering from an Arduino (5V), we recommend a 220Ω to 330Ω resistor for a standard indicator brightness.
3.7V Battery Power: To run these from a Li-ion or Li-Po battery, use a 100Ω to 120Ω resistor. This safely manages the voltage gap as the battery moves from 3.7V to 4.2V, ensuring the red color remains consistent.
The "Power" Light: This is the best LED for a "Main Power" indicator. Connect it directly after your power switch (with a resistor) to give immediate visual feedback that your robot is live.
Panel Mounting: If you are building a custom chassis, use a 5mm plastic LED holder to secure these into your panel. The diffused lens is superior for panels because it remains visible even when viewed from the side as the robot turns.

Package Includes

5 x 5mm Red Diffused DIP LEDs

Disclaimer Images are for reference; actual red saturation may vary slightly by production batch. DO NOT connect directly to a power source without a current-limiting resistor, as this will lead to immediate failure of the LED.
