Color temperatures in lightbulbs are known as the Kelvin levels. But William Thomas was a “bass-akwards” kind of guy: the higher a Kelvin level, the cooler the color temperature will be.

Most office designers recommend a “bright white” color temperature for your home office. You should be looking for color temperatures of between 4000K and 5000K to achieve the recommended temperature.

Standard LED light bulbs can easily achieve these Kelvin levels. They also give off a calming blue color tone which is ideal for productivity. You should note that the sunlight given off over the midday period is around 5000K. Natural sunny light is the best for working and has also been proven to improve your mood.
