What is the difference between cool white and warm white LED bulbs?

The main differences between cold white and warm white LED bulbs are reflected in color temperature, brightness and applicable scenarios. The following is a specific comparison:

Color temperature

• Cold white LED bulb: The color temperature is usually between 5500K and 7500K. Some people believe that 7000K and above is cold white. The higher the color temperature, the closer the light color is to blue, giving people a calm and fresh feeling.
• Warm white LED bulb: The color temperature is usually around 2700K. Some people believe that 3000K to 3500K are all called warm white. The lower the color temperature, the more red and yellow the light color is, giving people a warm and comfortable feeling.

Brightness

• Cold white LED bulb: The light is close to natural light, bright and clear, which helps to improve people’s attention and work efficiency.
• Warm white LED bulb: The light is soft and not too dazzling, suitable for creating a warm and comfortable atmosphere.

Applicable scenarios

• Cold white LED bulbs: Suitable for places that require bright lighting, such as offices, conference rooms, classrooms, library reading rooms, exhibition windows, etc. In these occasions, cool white light can provide better lighting effects, help maintain concentration and improve work efficiency.
• Warm white LED bulbs: suitable for places where a warm and comfortable atmosphere needs to be created, such as homes, residences, dormitories, hospitals, hotels, etc. In these occasions, warm white light can create a comfortable and relaxing environment, which helps to relieve fatigue and relax the mood.
• In addition, in terms of eye protection, warm white LED bulbs are usually more friendly to the eyes. Because the proportion of blue light in warm white light is relatively low, it is less irritating to the eyes and helps to reduce visual fatigue. However, due to the high proportion of blue light in cool white LED bulb, long-term exposure may cause a certain burden on the eyes. Therefore, when choosing LED bulb, you can choose the appropriate color temperature according to specific needs and scenarios.

In summary, there are differences in color temperature, brightness and applicable scenarios between cool white and warm white LED bulbs. When choosing, you can decide which color temperature LED bulb to use according to personal preferences and specific needs.
