What is the difference between 2700K and 5000K?
The K stands for Kelvin. The Kelvin temperature of a bulb refers to the actual colour of the light and is a comparison to natural outdoor light. A 2700K lamp has a warmer tone than a 5000K lamp. An incandescent lamp is 2700K, a warm white fluorescent lamp is 3000K, a cool white fluorescent lamp is 4100K and noon, outdoor sunlight is about 6000K. The 2700K matches the warm soft light colour of candlelight, firelight or an ordinary incandescent bulb. The 5000K lamp produces a much whiter light more closely associated with sun light. The advantage of this 5000K light colour is that it increases contrast. Black becomes blacker, white become whiter. Printed material (black type on white paper) is easier to read under 5000K light. Therefore, this lamp makes an excellent reading light and can help reduce eye fatigue.
