Health Effects in The Metal Halide Spectrum

Metal halide lamps are widely used in commercial lighting, especially in jewelry stores, clothing stores, etc. Metal halide lamps contain ultraviolet and infrared rays. Metal halide lamps with high color temperature also contain more blue light components, which are harmful to human eyes. Long-term close use of metal halide lamps will cause skin stains. 

As shown in the right figure, LED lighting Before the light source appeared, due to the good lighting effect of metal halide lamps, high color rendering, and no alternative light source, this issue was rarely mentioned. LED jewelry counter lighting solved the problem of ultraviolet and infrared radiation. However, many jewelry LED light sources with higher color temperature are used for lighting, resulting in a greater impact of blue light on the retina than metal halide lamps; metal halide lamps are still widely used and need to be used reasonably.
