There are several important factors that nail salons need to consider when choosing spotlights. Firstly, the color temperature. Color temperature can affect the color of light, thereby affecting customers' perception of nail art effects. Generally speaking, nail salons will choose cool white light or natural light with a color temperature between 5000K and 6500K, because this type of light can present the nail color more realistically and avoid color distortion caused by color temperature deviation. Next is the Color Rendering Index (CRI). The higher the color rendering index, the stronger the ability of light to reproduce the color of objects. For nail salons, spotlights with a color rendering index of 90 or above are an ideal choice because they can ensure that customers' nail colors look more natural and realistic.

In addition, the brightness and illumination angle of the spotlight are also important factors to consider. The brightness of the spotlight should be moderate, providing sufficient illumination without causing glare. The irradiation angle should be flexible and adjustable to meet different nail art needs and the shape of the customer's hand. Finally, the safety and durability of spotlights are also factors that cannot be ignored. High quality spotlights should have anti glare, anti ultraviolet and other functions, and have a long service life, able to withstand frequent use.
