Performance requirements for bedroom lamps

When the writing desk lamp is in the normal working position, there are three main optical performance requirements

(2) Desktop illumination requirements
The working area illuminated by the table lamp shall be 250lx - 500lx, and the minimum illumination shall be ≥ 120lx.
