In our homes we really only need to understand the difference between warm and cool light.
Cool light vs daylight. On the other hand daylight is a white light that is best for parking lot lights shopping centers streets and garages. This has nothing to do with actual heat from a light bulb but only with the appearance of the light. Cool white bulbs are known to help with concentration in classrooms and productivity at the work place.
Blue spectrum in Cool White and Daylight helps people to be awake and productive. Light bulbs with a blue and cool sensation are called daylight bulbs. Bulbs that provide light at around 6500K are considered daylight bulbs and these have a definite blue and cool sensation to them.
Pure White is not very warm. Daylight ranges from Blue-White 5000K to Bright Blue 6500K. I have cool white lights for my outdoor security and utility lighting because they are brighter than LEDs with a lower color temperature.
These descriptions refer to the Kelvin scale and the kind of light each bulb emits. The light appears as a bright neutral white that shades into blue at the upper end of this range. In contrast the soft white LED light bulbs produce light that has a color temperature range of 3000K to 2700K.
Light bulbs - the different types of light - WARM WHITE vs COOL DAYLIGHT energy saver. Daylight bulbs have color temperatures that begin at 4600K and can range up 6500K or higher. Cool white bulbs that provide light between 3700K and 5000K have a slightly blue feel to them and are considered to be.
Cool White ranges from Yellow-White 3000K to White 4000K to Blue-White 5000K. Warm Light is relaxing which helps people to calm down and prepare for sleep. Which is brighter cool white or daylight LED.
