Blue light is measured in kelvins as opposed to lumens (which is the measure of light commonly used for sodium and dual spectrum lamps), the higher the kelvin value the more plant usable light the lamp gives out. Higher kelvin ratings result in healthier plants, shorter internodal length and increased yields later in life.
