Introduction

Cotton grading room simulated daylight lighting uses artificial lighting units to simulate ideal natural daylight in moderately cloudy northern latitudes condition. This document specifies the technical requirements of lighting quality, light intensity, lighting conditions, and lighting units for simulated daylight lighting in cotton grading rooms. Technical requirements such as requirements and installation methods, environmental color and maintenance of lighting equipment. These technical requirements are used to ensure that the cotton in the cotton grading room and The consistency of the color presented under ideal natural sunlight conditions ensures the accuracy and reliability of the cotton quality inspection results.
