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.
