The PLMT Library
Light, explained by the engineer behind it.
Books on photobiomodulation, brain injury care, and regenerative medicine — by David Christenson, Founder and CTO of Neurocare PRO and developer of Pulsed Light Medical Technology (PLMT).
Volume 01 · Available Now
Red Light Therapy 2.0
The Power of Pulsed Light Medical Technology for Healing
Red light therapy, without the influencer filter.
The light-therapy market is flooded with misinformation and weak devices — wattage confused with efficacy, red confused with near-infrared, cosmetic panels sold as medical. This book is the grounded guide: engineering, evidence, and clinical context from the innovator behind PLMT, including why pulsed light outperforms continuous wave and how wavelength, dosage, frequency, and irradiance determine whether a device works.
What you’ll learn
- The history of light and healing
- The history of light therapy
- How red and near-infrared light interact with the body
- The power of pulsed light
- The wild west of red light therapy
- Medical grade vs. cosmetic red light panels
- Applications: pain, brain health, wounds, skin
- The science of dosage — evaluating products
- The future of light

Advanced Care for TBI
The Next Generation of Traumatic Brain Injury Care with Photobiomodulation
Go beyond the headlines. Explore the science.
Written by a technology developer and a TBI survivor, this book takes readers inside the questions that drive it — from persistent symptoms and cellular energy to the potential role of light-based approaches in neurological recovery. TBI is surrounded by misunderstanding: a person can survive a concussion, accident, fall, or sports injury and keep struggling months or years later with brain fog, memory problems, headaches, fatigue, sleep disruption, and dizziness — while scans show little explaining it.
What you’ll learn
- Why TBI symptoms persist long after the injury
- Neuroinflammation, circulation, and cellular energy
- Diffuse axonal and white-matter damage
- Frontal, temporal lobe & brain-stem involvement
- The brain-gut axis in recovery
- Photobiomodulation & PLMT research
- Recovery beyond symptom management
