Product Description The 8mm Blue Straw Hat LED delivers a deep, vibrant royal blue light with an exceptionally wide dispersion angle. Specifically designed with a "Straw Hat" low-profile lens, this LED spreads its light across a 120-degree field, eliminating the narrow "spotlight" effect of traditional 8mm LEDs. The crystal-clear epoxy housing ensures high light transmission and a sharp, modern aesthetic. These LEDs are the top choice for automotive interior lighting, sci-fi themed robotics, and accent lighting where a smooth, blue flood effect is desired.

Key Features

  • Deep Blue Saturation: Provides a high-intensity royal blue hue (approx. 460nm–470nm).

  • Wide-Angle Dispersion: Flat-top design ensures light is spread evenly, making it ideal for panel backlighting.

  • Crystal Clear Lens: High-quality "water-clear" finish for maximum clarity and brightness.

  • Large Emitting Surface: The 8mm diameter provides a substantial glow that is highly visible even from a distance.

  • Rugged and Efficient: Low power consumption and long operational life (up to 50,000 hours).

Technical Details

  • Anode (+): Longer Lead

  • Cathode (-): Shorter Lead (Indicated by a flat edge on the LED rim)

  • Wave Length: 460nm – 470nm

  • Operating Temperature: -25°C to +85°C

  • Soldering Temp: 260°C for less than 5 seconds

Prototyping and Engineering Tips from Robogears

  • Wide-Angle Backlighting: These are the best choice for illuminating a 3D-printed lithophane or a translucent acrylic panel from behind. Because the light spreads out immediately, you get fewer "hot spots" and a more even glow.

  • Current Limiting: Always use a resistor! If powering from a 5V source (like an Arduino), a 100Ω to 220Ω resistor is recommended to keep the current at a safe 20mA.

  • High-Density Arrays: Due to their flat tops, you can mount these very close to a front panel or diffuser without the LED physically touching the surface, allowing for thinner device designs.

  • Mix and Match: Use these alongside the 8mm Straw Hat White LEDs to create custom multi-color indicator panels or decorative light strings.

Package Includes

  • 5 x 8mm Blue Straw Hat LEDs
