How we test
Every comparative test on Radiance follows the same procedure. We buy every product anonymously at regular retail, at full price, from our own budget. No manufacturer is informed of a test, sends samples or sees results before publication. Laboratory measurements are carried out in line with recognized standards such as ISO 22716 wherever the category allows it, and the criteria are fixed in writing before the first product is opened.
Who signs off
No ranking is published without the written sign-off of our standing review committee, whose members and credentials appear on every test report. The committee checks the methodology, the measurements and every verdict sentence against the data.
Independence
We accept no sponsored placements, no free samples and no payment for rankings. Product links point to neutral retailers; whether a reader buys anything changes nothing about a verdict.
Corrections
Careful editing does not make us infallible. Substantiated corrections reach us at labman-trades@pm.me and are applied promptly, with a note on the article where the change is material.
