We can also divide colour temperature by Kelvin color.
4000k color temperature. Light bulbs with color temperatures of 4500K and above will give off a blue-white light that mimics daylight. Light used in specialist daylight lamps. Notably this temperature band resembles sunlight during the morning and afternoon.
4000K is approaching sunlight colour temperatures but still a bit on the warm side. Considering all the above factors a 4000K LED bulb is the best color temperature for your kitchen. Our recommendation overall is 4000K light Natural White color is the best office lighting color temperature for eyes and health with flicker-free.
Color temperatures between 3100K and 4500K are referred to as cool white or bright white Light bulbs within this range will emit a more neutral white light and may even have a slightly blue tint. You will find this color temperature in cooking kitchens retail stores and daytime offices. 4000K is a great temperature that has a perfect mix of color that is not too yellow and not too blue.
In general most warehouse lighting and outdoor lighting is 5000K often called bright white as its a close representation of sunlight. Both 4000K and 5000K can each look great. First we would like to show you 3000k4000k5000k colour temp from this picture 3000k light temperature features more red yellow or orange range.
3000K is a little bit more white but is still in the warm range. Soft White 2700K 3000K Bright WhiteCool White 3500K 4100K and Daylight 5000K 6500K. Its blue light damage will be a little higher than the 3000K color temperature it still can be within the acceptable range as long as we pay more attention to let the eyes rest more 4000K color temperature range is also the widest application.
4000k is a typical color temperature for retail establishments and offices. A standard 60 W bulb will give a warm glow of about 2700K while most fluorescent lamps have a white light that is mostly neutral of. These lights are bright and offer no favor to the warm or cool side of the Kelvin scale.
