The LED technology has new innovations and options to the lighting industry. one of those recent innovations: Color and Wattage selectable LED fixture. With the selectable CCT, it brings benefit to easily customize the temperature color to fir your needs on site. It greatly help save time and money during the design process and or, simply, change of mind.
The color temperature ranges from yellow or blue of light emitted as appears. The warmer of the light sources can have a low CCT (2200-3000K) which appears more yellow or orange. For a 'brighter' or cool light source, would have a higher color temperature as 4000K and up; thus appear more blue in color.
Instead of ordering a fixture with a specific CCT, the CCT selectable allows you to change the setting on site with an adjustable switch.
