These lights are packed with bright tiny squares of LEDs. I didn't understand why they were called corn until my son mentioned that round smoothies with tiny squares are supposed to be grains like corn. They emit bright light 360 degrees and on a scale of 4700 Kelvin or higher. We have from white to blue. I used one of these in my tool shed which had a high wattage Cfl glass bulb. The second went into my work light on a cord, which can be seen in my photo I uploaded for this review.
