Why Trust the Numbers
No lab coat. No finger on the scale.
01 / The Formula
One Open Formula
Each metric is min-max normalized across the models we track, then scored as ten times the weighted sum. Each category publishes its own weights — shown here: LED face masks.
score = 10 × (0.25·wavelengths + 0.20·LED count + 0.15·irradiance + 0.10·session time + 0.10·cordless + 0.10·FDA status + 0.10·warranty)
02 / Data Sources
Official Sources Only
Every spec comes from the manufacturer's official product page — never from retailer listings, reviews, or forums. Each product page links the exact source its numbers came from.
03 / Update Cadence
Re-Verified Monthly
Specs are re-verified against the official pages on a monthly cycle, and scores are recomputed the day any data point changes or a model enters or leaves the list.
04 / What We Don't Do
No Sponsors, Ever
We don't lab-test. We don't show prices. And we don't sell placement — no brand can pay to move a score, because the formula only reads specs.
