The Original 5mm White Water Clear LED (Production Quality - Pack of 1000 Pcs) is an ultra-bright, commercial-grade through-hole light-emitting diode engineered for high-volume PCB manufacturing, direct illumination, and optical indication. Encapsulated in a standard T-1 3/4 (5mm) crystal-clear water-clear epoxy resin lens, it integrates a high-efficiency InGaN (Indium Gallium Nitride) semiconductor die that emits a focused, high-intensity 6000K–6500K cool white beam with a narrow 20° to 30° viewing angle. Built with high-conductivity pure copper leadframes for optimal heat dissipation and high-integrity internal gold-wire bonding, these LEDs deliver superior optical punch, high luminous efficacy, and tight batch-to-batch consistency across the entire 1000-piece production pack. They are widely utilized in flashlights, emergency lighting, backlights, optical sensors, automotive accents, and DIY electronics projects.

• DIY Robotics & Microcontroller Projects: High-brightness searchlights and headlamps on Arduino, ESP32, and Raspberry Pi robot chassis.

Usage Tips

• Always Use a Current-Limiting Resistor: **Never connect the LED directly across a voltage source without a series current-limiting resistor**, as unconstrained current will burn out the LED die instantly.
• Series Resistor Calculation Formula: R_series = (Vsupply - VF) / IF.
  • From a +5.0V Logic Rail (at IF = 15mA, VF = 3.0V): R = (5.0V - 3.0V) / 0.015A = 133Ω (Standard 150Ω or 220Ω, 1/4W resistor recommended).
  • From a +12.0V Supply (at IF = 15mA, VF = 3.0V): R = (12.0V - 3.0V) / 0.015A = 600Ω (Standard 560Ω or 680Ω, 1/4W resistor recommended).
  • From a +24.0V Industrial Rail (at IF = 15mA, VF = 3.0V): R = (24.0V - 3.0V) / 0.015A = 1400Ω (Standard 1.5kΩ, 1/2W power resistor recommended).
• Polarity Identification: Connect the longer lead to the positive rail (Anode +) and the shorter lead to ground or the low-side switch (Cathode -). If leads are already trimmed, the Cathode side is identified by the flat notched edge on the rim of the epoxy base.
• 3.3V Microcontroller Interfacing: Because the white LED forward drop is ~3.0V, driving directly from a 3.3V GPIO rail leaves only ~0.3V across the series resistor. Use a small 22Ω to 47Ω resistor for direct low-current driving (5mA–8mA), or drive via an NPN transistor (e.g., 2N2222/BC548) connected to a 5V rail for maximum brightness.
• Soldering Recommendations: Keep a minimum clearance of 2mm between the soldering iron tip and the bottom of the epoxy body. Limit soldering contact time to under 3–5 seconds at 260°C to protect the internal gold bonding wire from thermal stress.
