Gemstone color grading lights for diamond inspection and grading

Proper lighting is important for accurate diamond color grading, as variations in light sources can affect color perception. These grading lamps are designed to meet industry standards, providing uniform illumination free from UV interference, with balanced energy distribution, minimal heat emission, and a color temperature range of 5500K to 7200K. By offering a controlled and consistent light source, they enhance accuracy and comparability in diamond grading, making them an essential tool for gemologists and grading laboratories.
