Prices
- Every price comes from the seller’s own product page on the date shown. Where we confirmed it against the seller’s live product data the page says “Price checked”; otherwise it says “Listed” with the date it was recorded.
- Every “Visit” button opens that exact product at that seller, never a homepage or search page.
- Shipping, tax, bundles and promo codes vary by seller and aren’t included.
Order of lists
- Lists are sorted by lowest price by default; you can re-sort by number of sellers or A to Z. Whether a seller pays us a commission never changes the order.
Specs and photos
- Specs such as wavelengths, LED counts and irradiance are shown as the seller states them. We haven’t measured them, and sellers count LEDs, chips and diodes differently.
- Product photos come from each product’s own store page.
Uses
- A device appears under a use because of what it is sold as: a face mask under skin, a cap under hair growth. Recovery, sleep and pain-relief listings quote the maker or seller word for word, with a link to the source.
- We make no health claims of our own. Nothing on this site is medical advice.
