High coloring rendering LED packages of Ra85 or above with excellent color reproducibility are used in the Power Flex Slim Light and other products. High color rendering LEDs are recommended when true color reproduction or preventing color fade-out is required.

The average color rendering index (Ra) is an index of the color offset that occurs when the measured light source illuminates the color chart used for the color rendering evaluation in comparison with standard light as defined by JIS (Japan Industrial Standards).

This light source is also widely used to prevent deterioration from light since LEDs emit little heat or ultraviolet light.
