The Solar Meter Lie: Why “High Irradiance” Claims in Red Light Therapy are Often Fake

In the world of red light therapy, "Irradiance" (the power of the light) is everything. But as the market matures in 2026, a deceptive trend has emerged: Irradiance Inflation. Many brands claim power levels of 100mW/cm² or higher using cheap $20 solar power meters to "prove" it.

 

Here’s the catch: Solar meters are designed to measure the broad spectrum of the sun. When they hit the narrow, intense peak of a red LED, they "over-read" the energy by as much as 40%. At Vecaxo, we believe luxury is built on truth. We use laboratory-grade spectroradiometers to verify that our 660nm and 850nm peaks are precise. When you see our specs, you aren’t seeing a "marketing number"—you’re seeing a clinical dose. Before you buy a device based on a high number, ask for the spectrometer report. If they can’t provide it, the "power" might just be smoke and mirrors.
