Red Light Therapy Devices Aren’t All Equal: What Actually Matters | Part 1
transcript

Not all red light therapy devices are created equal. In Part 1 of this conversation, Dr. Ginger Bowler sits down with David Malone, a light-therapy device designer and manufacturer with 40 years of industry experience, to explain what actually matters in photobiomodulation—and what may be little more than marketing.
David traces the evolution of light therapy from early helium-neon lasers and veterinary applications to modern LED pads and panels. He explains red and near-infrared wavelengths, pulsing, treatment distance, skin contact, light penetration, overlapping LED coverage, FDA clearance, UL testing, and the engineering hidden inside a device.
In this episode:
• Red light versus near-infrared light
• What wavelength numbers actually mean
• The origins of pulsed light therapy
• Lasers versus LEDs
• Skin-contact pads versus stand-alone panels
• Why distance from the skin matters
• True wavelengths versus colored plastic lenses
• FDA 510(k) clearance and device testing
• The danger of copying a device without understanding its engineering
• The half-cent component that prevented a serious device failure
