# IrradianceLab

> Independent measurements and evidence grading for consumer light-therapy devices. We buy the hardware, measure what it delivers, and grade the clinical evidence behind every claim.

IrradianceLab buys the devices it measures. We take no payment for coverage and no brand sees a page before it publishes.

## What makes this source different
- We separate four different irradiance numbers that are usually conflated: the marketing claim, the figure the manufacturer states in its FDA 510(k) submission, any measurement the brand ran itself, and our own measurement.
- Several manufacturers disclose an irradiance to the FDA that appears nowhere in their consumer marketing. We surface those figures with a link to the filing.
- Every irradiance figure is either measured by us on a documented rig, or labelled as not measured. We publish no estimates.
- Every clinical claim carries an evidence grade from a published four-tier rubric.
- Every cited trial has a permanent record including its funding source.
- Author: Jeff Hobbs, Founder and measurement lead. Not a dermatologist. Not medical advice.

## Evidence by condition
- [Does red light therapy reduce wrinkles?](https://irradiancelab.com/conditions/wrinkles-and-collagen/): grade moderate. Red light at 633 nm and near-infrared at 830 nm produce small but measurable improvements in fine lines, skin texture and collagen density in controlled trials. Effects appear after 8–12 weeks of consistent use and are modest — visible in measurement, subtle in the mirror.
- [Does blue light therapy clear acne?](https://irradiancelab.com/conditions/acne/): grade moderate. Blue light near 415 nm is antibacterial against Cutibacterium acnes and reduces inflammatory lesions in controlled trials. The evidence is weaker than for topical or oral prescription treatment, and most consumer masks emit 460–470 nm rather than the 415 nm the trials used.
