(1) Downlight: Downlight is an essential light source for jewelers to identify and purchase jewelry, and it is only applicable to the space lighting of jewelry stores.

(2) Metal halide lamp: strong brightness and high light efficiency. But the light is too dazzling, the color rendering is poor, and it is easy to distort the color of diamonds, so it is not suitable for the lighting of counters and jewelry windows, only suitable for places with high ceilings.

(3) Projection halogen lamp: compact, flexible and easy to control. The sparkle of diamonds can be well presented, but ordinary halogen lamps have poor color rendering, yellow light, easy to distort the color of diamonds and short service life.

(4) Diamond halogen lamp (4500k): This is a professional diamond lighting lamp. The color rendering effect of light is high, and the projection effect of full spectrum is the artificial light source closest to natural light. In this light, every diamond can shine with the rotation of people's eyes, which better presents the charm of color and cutting. Compared with ordinary halogen lamps, it has the advantages of good color rendering and long service life, and can show the brilliant light of diamonds when applied to jewelry lighting.

In addition, optical fiber and led have the characteristics of soft and non-irritating light, rich light color, small thermal radiation and easy concealed installation, which are more suitable for the lighting of jewelry counters. If they can be properly designed and organically combined with the illuminated object, they will play the role of "icing on the cake".
