3W 680-690nm High-Power Deep Red / Near-Infrared LED – 60° Lens Integrated (2.0V - 2.2V)
Product Overview:
Deliver targeted spectral output with the 3W 680-690nm High-Power Deep Red / Near-Infrared LED. Operating within the effective 680nm to 690nm wavelength band, this high-power emitter bridges visible deep red light and near-infrared, making it a critical light source for medical phototherapy, biological research, and horticultural lighting systems.
Equipped with an integrated 60-degree optical beam lens, it concentrates radiant flux into a tight beam pattern for higher irradiance and deeper light penetration over target surfaces. Designed as a bare emitter, it allows complete mounting versatility for custom PCBs, aluminum heatsink modules, and specialized light arrays.
Key Features:
- Targeted 680-690nm Spectrum: Emits in the highly beneficial deep red / near-infrared window essential for mitochondrial stimulation and photosystem activation.
- Phototherapy & Medical Applications: Popular wavelength choice for red light therapy, tissue regeneration research, skin rejuvenation panels, and targeted photobiomodulation (PBM).
- Focused 60° Optical Lens: Concentrates light output into a 60-degree beam angle to maximize energy density and minimize stray light leakage.
- Forward Voltage (2.0V - 2.2V): Efficient electrical parameters designed for straightforward integration with standard LED drivers and control circuits.
- Bare Emitter Format: Direct thermal connection compatibility for mounting onto external aluminum heatsinks or custom circuit boards.

Critical Operating & Safety Guidelines:
- Current-Limiting Circuit Required: Operating at 2.0V – 2.2V DC, this LED must be driven using a dedicated Constant Current Driver (600mA–700mA) or a current-regulated circuit. Direct connection to a constant voltage supply without current regulation will instantly trigger thermal runaway and burn out the LED.
- External Aluminum Heatsink Required: High-power 3W LEDs produce significant localized heat. The emitter must be mounted directly onto an adequate external aluminum heatsink using thermal grease or thermally conductive adhesive prior to applying power.
- High-Intense Light Warning: Emits high-intensity deep red light. Do not look directly into the lens when operational. Wear suitable protective eyewear during testing and assembly.
