NeoPixel UV vs IR vs Mini LEDs: Specialized Applications (2026)

Last updated: December 2025

Beyond standard RGB LEDs, specialized NeoPixel variants open up exciting possibilities for unique applications. This guide compares UV (ultraviolet), IR (infrared), and Mini NeoPixels, helping you choose the right technology for your project’s specific needs.

🎯 Quick Overview

Understanding Specialized NeoPixels

UV NeoPixels

• Wavelength: 395-405nm (near UV)
• Key Features:
  • Creates glowing effects with fluorescent materials
  • Perfect for blacklight parties and art installations
  • Available in both 5mm through-hole and surface-mount formats

IR NeoPixels

• Wavelength: 850nm or 940nm
• Key Features:
  • Invisible illumination for night vision cameras
  • Ideal for security and surveillance
  • Can be used for proximity sensing

Mini NeoPixels

• Size: As small as 1.6mm x 1.6mm
• Key Features:
  • Ultra-compact form factor
  • Perfect for wearables and high-density displays
  • Available in various package sizes

Technical Comparison

1. Power Requirements

• UV NeoPixels: ~20mA per LED at 5V
