Difference 1: Different color temperature values. Cool white light has a color temperature of 5500-7500K, while warm white light has a color temperature of 3000-3500K. The lower the color temperature, the yellower the light; the higher the color temperature, the whiter the light. Difference 2: Different color rendering. Cool white light is very bright and has high color rendering, suitable for environments with operating space such as exhibition halls and kitchens. Warm white light appears dimmer, has low color rendering, can create an atmosphere, and is suitable for bedrooms, cafes, etc.

How to choose the color temperature of the lighting

1. Usage environment

When choosing the color temperature of the lighting, the needs of the usage environment should be considered first. Generally, the color temperature of lighting can be divided into three categories: cool white light, neutral white light, and warm white light. Cool white light usually has a color temperature of 5500K-7500K, high color rendering but very dazzling, more suitable for use in exhibition halls, etc. It is almost unsuitable for use in homes, except for the kitchen, which requires concentration for fine operations, and a high-color temperature light source is more suitable.

For other areas of the home, it is recommended to choose 2700K, 3000K, or 4000K warm white or neutral white light according to your preferences and needs. For example, areas such as the living room, entrance hall, and study still have certain requirements for lighting, so a 4000K light source is more suitable. For areas like the bedroom, warm white light is sufficient, as brighter light colors can also affect people's desire to fall asleep, isn't it?

2. Home color scheme

On the other hand, the choice of lighting color temperature can also refer to the home color scheme. For example, if the walls are painted with colored paint, a light source of around 4000K will not be dazzling and can maximize the restoration of the original color of the color. If the home mainly uses solid wood furniture, such as black walnut, cherry, and white oak, pairing it with a warm white light of around 3000K can better reflect its texture and color.
