One eliminates the reflection. There is no glare reflection to the first condition of comfort.

Like the background light is too strong, the computer screen is glare and the various lighting lighting design is not good, the difficulty of visual recognition is increased, and the working time is relatively extended.

Three light colors are warm. The creation of the atmosphere can dominate the color of the light source, and the color temperature that expresses the light texture is the protagonist. The higher the color temperature value, the more the light is biased toward blue, which creates a calmer atmosphere; the lower the color temperature, the closer to the candlelight yellow-red, the more soothing mood. In fact, the closer the light is to natural light, the better the artificial lighting should be combined with natural lighting to create a comfortable lighting environment. With natural light, you can save 30% of your electricity usage during the summer.
