Switching this allows you to select warm white 3000K or cool white 4000K.
3k light color. Cylindrical-coordinate representations also known as HSL of color eedd82 hue. If you really cant decide even after years of counseling you dont always have to. Many of our customers are trying to upgrade from this color of bulbs as they feel that it makes their vehicle look more dated than it is.
LED lights come in various correlated color temperature CCT values such as warm yellowish glow and cool white light among others KRM Light. Color Temp CCT. Since fixtures using discharge type lamps produce a light of a considerably higher color temperature than do tungsten lamps using the two in conjunction could potentially produce a stark contrast so sometimes fixtures with HID lamps commonly producing light of 60007000 K are fitted with 3200 K filters to emulate tungsten light.
The lower kelvin lights are cost and energy efficient safer better for human health and wildlife conservation and contribute less to skyglow. Colour temperature switchable lighting contains multiple colour temperatures in one. Color switching model is provided with a switch behind the unit to toggle between warm white 3000K CCT neutral white 4000K CCT and cool white 50000K CCT available in 7 and 9 configurations only.
3000K 4000K and 5000K are the Kelvin temperature of the light which as you mentioned impacts the color. May be a switch on the lights themselves. You may have seen Kelvin K or Color Temperature CCT before.
CCT is defined in degrees Kelvin. The most common temperature offering you will find in this range is 2700. Light bulb color temperature is represented in the unit of absolute temperature Kelvin noted by the symbol K.
Correlated colour temperature is measured in degrees Kelvin on a scale from 1000 to 10000. LEDs are available in warm colors low k to match the yellowish light of incandescent bulbs but you can also choose cooler colors high k with whiter or bluer light. It is often called Warm White.
