LED vs Laser Therapy: What the Research Suggests About Dose, Irradiance, and Delivery
Why the practical difference may be less about coherence and more about controlling dose. In my experience, I’ve been to […]
How Much Light Is Your Panel Actually Delivering?
Red light therapy has a dosing problem, and it’s not the one most people think about. The research is real.
Stabilizing Optical Dose in LED-Based Photobiomodulation Systems
Why session duration alone cannot determine delivered optical dose, and how measurement-informed stabilization changes what can be known. Much of
Focus on measurement and clarity
I’ve always been a bit skeptical of how much actual power can be delivered from an LED. A driving motivator
Measuring what actually matters: NIST-traceable irradiance measurement in a handheld puck
Red light therapy panels are now everywhere — from handheld devices to full-body panels. Nearly all of them advertise numbers
From LED Watts to Delivered Dose: Reconciling Power Claims in Red Light Therapy
An engineering analysis of electrical input, optical output, irradiance, and delivered dose consistency. For red light therapy and photobiomodulation hardware,
