Is red light alone enough? In Part 2, Dr. Ginger Bowler and 40-year light-therapy industry veteran David Malone explore why photobiomodulation devices may use combinations of red, near-infrared, blue, and green light rather than relying on a single wavelength.
David explains how combining red and infrared appeared to reduce treatment plateaus, where pulsing originated, what Nogier and Solfeggio frequencies are, how duty cycle works, and why different wavelengths penetrate the body at different depths.
They also discuss the addition of blue and green light, observations reported by practitioners and device users, Doppler testing, circulation, treatment duration, and what David has learned through decades of developing LED light-therapy systems.
In this episode:
• Why red light alone may be only part of the story
• Red and near-infrared combinations
• The discovery of infrared light
• Why treatment responses may plateau
• The origin of pulsed light therapy
• Nogier and Solfeggio frequencies
• Cymatics and frequency patterns
• Blue and green light applications
• Duty cycle explained in plain language
• How deeply different wavelengths penetrate
• How treatment duration was evaluated
• Doppler testing and circulation
