The warm light is relatively soft, which will not produce strong reflection and glare, reduce eye fatigue and improve visual comfort at night.

Finally, warm light can also create a romantic and warm atmosphere. In the city streets at night, warm street lamps can give people a warm and romantic feeling, which increases the cultural atmosphere and humanistic feelings of the city.

Warm color light can not only relieve fatigue and anxiety at night, but also reduce glare and eye fatigue and improve visual comfort at night.
