3000k vs 4000k LED General Overview

A 3000k LED is generally on the warm side of the light color spectrum. It produces a warm white, soft white, or yellowish color of light. Warm light can be anything from 3000k and under.

The 3000k color temperature is more pleasing and better for the eyes. It generates a weaker blue light which can badly damage the eyes over prolonged exposure and has adverse effects to your body, such as sleep

Generally, 3000k color temperature is chosen by customers for warmer lighting and a more earthy ambiance at home.

This kind of lighting is designed for a cozy and relaxed atmosphere, rather than a working and active environment. It can activate the production of melatonin, a hormone in your body, which makes you sleepy.

4000k LED 

A 4000k LED is a brighter and cooler white color temperature than a 3000k LED. Cool white can be anything from 4000k and above. It is sometimes called a neutral white color because it is not too warm nor too bright. 

A study published by the University of Toronto shows that bright light, like this one, can affect the emotional intensity and decision-making process of a person.

Bright light usually creates a positive environment that can make a person more alert and attentive. A 4000k color temperature is good if you want to create an energetic yet relaxing environment.
