Does the USB gift make the main lamp USB-powered, and does Three colors prove brightness dimming?
No. The main fixture is listed as AC-powered. Confirm actual gift contents and brightness-control compatibility separately from tone switching.
What materials are described?
Iron/aluminum body with painted finish fields. Round and Square each offer Black and White; generic black-only wording does not describe every option.
What dimensions should I check?
Round/Square labels do not provide dimensions. Depth, weight, plate, fixing layout and actual LED arrangement unspecified.
What power or control details should I confirm?
SMD LED included; generic more-than 20 chips and Wedge do not establish replaceable bulb quantity. Three colors current option, exact Kelvin/sequence unspecified. Dimmable Yes does not identify brightness-control protocol. AC90–260V versus AC110–220V references require actual rating checks. Power, driver and service method unspecified.
What comes with the selected version?
Authored package lists fixture, accessories, guide and USB night-light gift. Confirm actual selected package and gift inclusion; the gift does not establish USB power for the main AC ceiling fixture.
How should it be set up?
Have a qualified installer confirm actual dimensions, weight, structural support, fixing layout, clearances and delivered electrical rating before connection. Resolve the selected socket or LED assembly, source quantity and inclusion, driver, input, power limits and control package using actual labels and instructions. Fixture input is not a universal bulb voltage. Follow actual ceiling-mounting or suspension instructions. Confirm canopy, cord components, body depth, adjustment limits and final installed height before fitting.
What care is appropriate?
Isolate actual power and allow sources to cool according to delivered instructions before cleaning or servicing. Support the selected glass, acrylic, resin, wood, plastic, shade and body parts as applicable while dusting gently using actual material/coating instructions. Avoid impacts, soaking, abrasives and unverified solvents. Follow the documented source, driver, control and mounting service procedures. Do not force joints, twist wiring or open sealed parts without a supplied procedure; have damaged electrical or structural parts assessed before reuse.
