What is CRI? Color Rendering Index. CRI is a measure of a light source's ability to show object colors "realistically" or "naturally" compared to daylight, which has a CRI of 100 and represents the maximum value. The beam angles for the Sea Dragon lights are shown as the true, tested “in-air” (above water) beam angle. Underwater, due to light refraction, the angle tightens to approximately 33% less. 

Beam Angle: The beam angles for the Sea Dragon lights are shown as the true, tested “in-air” (above water) beam angle. Underwater, due to light refraction, the angle tightens to approximately 33% less. For underwater video or photo, you want a wide or flood beam. A spot beam is great for poking in cracks and crevices, but will show as a dancing bright dot in your underwater photos and video. The higher the degree, the wider the beam.
