Its common to see a LED Light bulb labeled like this.
Led k rating. Light bulb color temperature is represented in the unit of absolute temperature Kelvin noted by the symbol K. Color temperature is specified in degrees Kelvin K which is a temperature scale in which zero occurs at absolute zero and each degree equals one Kelvin. Color temperatures higher than 3500K are typically used for.

The K rating printed on modern commercial lights applies for non-incandescent lights such as LEDs fluorescent lighting etc is different from the Kelvin rating used on black body generators. Due to other efficiency factors currently available cool white LED packages eg 6500 K are approximately 20 more efficacious than warm white LED packages eg 3000 K as shown in Figure 2.
That means LEDs are able to use light and energy more efficiently in a multitude of applications. If youre looking for the brightest possible light ignore all the other ratings. Remember to connect the LED the correct way round.
