Four Color Temperatures
Gritin offers amber at 2000K, warm white at 3000K, natural white at 4500K and white at 6000K, a wider spread than a light with a single warm and a single cool setting. The range matters because the two ends do different jobs. Amber and warm white contain far less short-wavelength blue light, the part of the spectrum that most strongly suppresses melatonin, so they are the settings for reading in the hour before sleep. Natural white and white render colors more accurately and give crisper contrast, which helps with small print, dark yarn and fine stitches. Having both on one light means you don't have to choose between a sleep-friendly lamp and a work lamp. Lighting options are among the most praised things about it, with almost no complaints, and one owner who reads beside a sleeping partner finds the yellow light more soothing before bed.
