Proper store lighting can attract more customers to any establishment, help sell more product, and strengthen a store's image. Many designers argue that the most important element of a store's design may be its lighting. Unfortunately, lighting is often the most neglected component of store design.
When choosing the lighting for any store or display cases, here are a few ideas to keep in mind.
Ceiling Height : The height of a store's ceiling is one of the most important factors that goes into a plan for lighting a jewelry store in such a way that the merchandise looks spectacular. As the source of light moves farther away from the merchandise the power and intensity of the light diminishes. Stores with higher ceilings (over 9 ') face some challenges with lighting. Stores with ceiling that are taller either have to use more lights that are spaced closer together to illuminate a showcase or bring the light source closer by dropping down a track or using a pendant.
Color : The color of light is measure in Kelvin (temperature). The higher the temperature (Kelvin) reading the cooler the color of light and the lower the temperature the warmer the color. For example a light that is 3000K would be a warmer color and a light that is 4000K would be a cooler light. As the temperature of light gets too high (over 4200K) the color of the light begins to take on a blue quality. Lights that are in the 5500K to 6500K will look "blue" to the eye.
Bulb Life / Quality : How long a bulb is expected to last is based upon its "rated life". The better bulbs have a rated life in excess of 10,000 hours. The quality of a bulb can also be measured by its CRI (Color Rendition Index). The higher the CRI of a bulb the better the quality of the light that it projects will be. CRI numbers over 80 signify a very high quality of light. CRI numbers over 90 signify an exemplary quality of light.
Power of Light : The power of a bulb is measured in lumens. The amount of light that is generated is measured in Lux or, more commonly, in foot-candles ("fc"). The higher the lumens the higher the amount of foot-candles that will be generated by the bulb.
Different Light Sources : There are three main sources of light that are used in Jewelry stores. They are (1) Ceramic Metal Halide (2) Halogen (3) Fluorescent. LED technology is being used more and more but is still far behind the main three. The best source of lighting for jewelry is still Ceramic Metal Halide. This is due to its qualities. They are energy efficient, powerful (lumens over 6000), come in warm and cool colors (3000K to 4200K) has excellent CRI (over 80 and in most cases over 90 CRI) and can provide foot-candles that can exceed 400. Halogens are hot, have lower CRI's, do not maintain their color …
