The mandland M025 listing, bullet by bullet
Five bullets: a touch button on the head, for painting miniatures, repairing electronics and diamond painting; 10× magnification through a 4.3-inch real glass lens; five colour temperatures from 3000 to 6500 K, each dimmable from 10 to 100 %, with memory; a swing arm with four springs and three joints and a tool-free clamp for surfaces up to 2.1 inches; and a box with the lamp, a manual and an adapter.
A glass lens without a dioptre on the mandland
4.3 inches of real glass, sold as 10×. Glass resists scratches better than acrylic. The strength is not expressed in dioptres, which is how the Showlite, SEMPLIX, goobay and Lumeno lamps reviewed here state theirs.
Light that can be tuned
Warm light for reading, cool light for colour work, and brightness in each: the third bullet describes a flexible light, and a memory saves the choice. No lumen figure goes with it.
Claims about comfort
The second bullet promises an end to eye strain and dizziness during long sessions. The page reports it as the maker’s wording; nothing on the listing measures it.
Availability
At the last look-up, the German, French and Spanish Amazon stores were asking 32 € to 49 €.
It is sold in the British Amazon store as well, in its own currency, which the euro figures above leave out on purpose.
The American and Italian Amazon stores returned no entry, so the buy button there opens a search rather than a missing page.
