Xiaomi Mi LED Desk Lamp 1S: full specs

The official Xiaomi global specs page (source) identifies the exact model as Mi LED Desk Lamp 1S, Model no MJTD01SYL, and states verbatim: Luminous flux 520 lm, Color range 2600 K - 5000 K, Color rendering index Ra 90, Rated input power 9 W, Rated input 220-240 V with an included Adapter (corded), and Brightness range 1%-100% via a flicker-free constant-current analog dimming rotary dial with continuous 2600-5000K color-temperature tuning (hence stepless brightness and stepless CCT). The English TechPunt retailer page (corroboration) independently confirms the same 1S model with 520 lumens, Ra 90, four lighting modes, dial control, and 25,000h life, and lists a EU price of EUR 39.95. No US MSRP was available on any fetchable page, so price is left blank rather than converted or guessed; weight and USB/Qi/auto-dimming-sensor were not stated on any fetched page and are left blank.
