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.
Red Focus Light
Some diving conditions make it difficult for your camera to focus on the subject, for example while diving at night or under low light. A red focus light will help illuminate your subject with enough contrast to allow your camera to focus (auto or manually) and create a better, sharper image. The red light is also undetectable by marine life and won't scare them into hiding like a bright white light will.
