In life, our commonly used 220V indoor ceiling light has white light and yellow light. The technical terms in LEDs are called positive white light and warm white light. Each light color has a color temperature band, which is a unit of measurement that indicates that light contains color components. The unit of measurement is "K", we only need to understand its surface meaning, and the deeper meaning needs to be explored by ourselves.
There is little difference between the household solar indoor light and the 220V mains ceiling light, one is to use AC high voltage to work, and the other is to use solar energy. The input method is different, but the output mode is the same, with the LED light source as the emitter. To achieve white and yellow light, you only need to replace the LED lamp beads with different color temperatures.
It can be seen from the table that everyone's heart requirements are different, and there will be different luminous colors in different environments. If it is used in the countryside, I recommend using a color temperature of 6000K, because the countryside is basically for the elderly, the 6000K color temperature looks whiter and brighter to see more clearly, 4500K looks more comfortable for natural light, and if it is used in the bedroom, you can use warm white light of about 3000K to be warmer. The color temperature of conventional home solar indoor lights is around 6000K, and we can choose according to our own requirements when choosing.
