The color temperature selection of LED tunnel lights can be determined according to the actual needs and application environment. In general, the following are several common choices for the color temperature of LED tunnel lights:

Natural white light (4000K-5000K) : The color temperature range of natural white light is usually between 4000K and 5000K, with high color reducibility and recognition. This color temperature LED tunnel light can provide a more realistic light effect, making it easier for drivers to identify roads, signs and other vehicles. At the same time, natural white light can also reduce the risk of visual fatigue and glare.

White light (5000K-6000K) : White light color temperature range between 5000K to 6000K, with high brightness and clarity. This color temperature LED tunnel light can provide bright lighting effects, suitable for places requiring higher brightness. However, the higher color temperature of white light may also increase the driver’s sense of glare, which needs to be properly controlled.

Warm white light (2700K-3500K) : Warm white light color temperature range is usually between 2700K and 3500K, with a lower color temperature and soft lighting effect. This color temperature LED tunnel light can provide a warm, comfortable environment, but relatively may not be as visually clear as natural or white light.
It should be noted that the lighting environment in the tunnel is different from other applications. When choosing the color temperature of the LED tunnel light, the following factors should be considered:

The driver’s visual needs and comfort: The choice of color temperature should be aimed at providing good visual clarity and comfort, avoiding excessive brightness and glare.

The recognition of road surface and signs: the color temperature also has an impact on the recognition of road surface and signs, and the color temperature that can accurately display color and details should be selected.

Surrounding environment: The brightness and color of the surrounding environment also need to be considered to ensure that the lighting is in harmony with the surrounding environment.

The best LED tunnel light color temperature selection should be evaluated and tested according to the actual situation, combined with the above factors for comprehensive judgment. At the same time, it is recommended to follow the relevant standards and specifications, and cooperate with professional designers or contractors to ensure that the lighting design meets the actual needs and safety requirements.

Since its founding in 1993, with its strong advantages in the field of LED technology innovation and practical application, Shanghai Sanji has provided lighting products and system solutions for more than 2,500 sets of highways and urban tunnels across the country to ensure road safety and efficient operation and management.
