Product Details
✓Built-in breathing/fading effect — smooth pulse - 20 Red fading/breathing LEDs with built-in fade circuit that smoothly pulse in and out for mood lighting, ambient props, theatrical effects, and gentle visual signaling — integrated fade circuit operates on DC power
✓Breathing red output at 620-630nm - Emits 620-630nm red light with a built-in fade IC that drives a smooth pulsing brightness ramp from a steady DC source; no programming step is part of operation. Forward voltage is 2-3V with an appropriate series resistor at 20mA typical drive current.
✓Standard radial through-hole package - Radial DIP body with two leads on standard 2.54mm pitch seats in breadboards, perfboard, and PCB through-holes for hand soldering. Polarity-sensitive: longer lead is anode (+), shorter lead is cathode (−). Internal fade IC is fully contained within the epoxy lens.
✓Polarity and resistor reference - Through-hole LEDs are polarity-sensitive: longer lead is anode (+), shorter lead is cathode (−). For 20mA drive current with a 1.8-2.2V LED, use a series resistor of 150Ω 1/4W on 5V, 360Ω 1/4W on 9V, 510Ω 1/4W on 12V, or 680Ω 1/2W on 15V.
✓Mood and ambient lighting uses - Smooth breathing pulse at 620-630nm suits mood lighting panels, theatrical breathing effects, and ambient accent glow for art installations and props. Pulse timing is handled entirely by the integrated fade IC at 20mA typical drive current for gentle, repeating visual signals.
