For those who spend lots of time indoors, installing LED lights that mimic natural light may be a top priority.
The color temperature of natural light can be difficult to pinpoint as it can range from 4000K to 6500K or higher, depending on the time of day, weather, latitude and season.
If you're after the warmer feel of natural sunshine (as opposed to daylight), 4000K may be a great option for you. 4000K can be described as early-morning or late-afternoon sunshine that comes in through a south-facing window.
5000K and higher color temperatures are also close approximations of natural light, but they are more aligned with natural daylight, rather than natural sunlight. Think of a more neutral, white light coming in from a north-facing window on an overcast day.
