WL-P3EP4242IR140-850 High-Power 3W IR Emitter LED (850nm, 700mA, 140°)

Upgrade your night vision systems, CCTV illuminators, and optical sensing platforms with the WL-P3EP4242IR140-850 high-power Infrared (IR) LED emitter. Operating at a peak wavelength of 850nm, this 3-Watt Infrared LED produces intense, high-efficiency radiant flux designed for long-range night vision illumination. Cameras and CMOS image sensors are exceptionally sensitive to the 850nm spectrum, providing bright, clear monochromatic video capturing in pitch-black conditions.

Engineered to operate at a continuous forward current of 700mA, this LED features an ultra-wide 140° viewing angle, making it ideal for broad, uniform floodlighting without dark spots or hot-center vignetting. Housed in a ceramic 4242-style surface-mount package with a high-thermal-conductivity base, proper mounting to an aluminum PCB heatsink (Star-PCB) is essential to ensure long operational lifespan and stable radiometric output. It is the premier choice for custom surveillance IR floodlights, automated license plate recognition (ALPR) systems, 3D gesture tracking, and machine vision projects.

Key Features:

• 850nm Peak Wavelength: Highly efficient spectrum matching maximum spectral sensitivity of security cameras and CMOS sensors.
