## Definition

Red light therapy devices are consumer and clinical-grade instruments that deliver calibrated photobiomodulation wavelengths (typically 630–670nm red and 810–860nm near-infrared) to target tissue. Device categories include full-body panels, full-face LED masks, handheld wands, and targeted orbital devices. Critical specifications include: wavelength accuracy (LED binning tolerance), irradiance at treatment distance (mW/cm²), LED driver type (PWM vs. constant current), total fluence per session (J/cm²), and form factor weight. Full-face masks typically deliver 5–15 mW/cm² across approximately 600 cm², while targeted orbital devices concentrate >30 mW/cm² on approximately 12 cm². Most consumer devices use 630nm LEDs (approximately 70% of optimal cytochrome c oxidase absorption) due to lower cost. Clinical-grade devices use tighter wavelength bins (±2nm at 660nm) verified by spectrometer.
