*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.
Avoid using this Sea Dragon light above water for prolonged periods of time
The light is designed for underwater use and water is needed to displace heat. The metal light head at full power will reach temperature of about 140F (60C) degrees within a few minutes, which may cause burning if touched. A thermal sensor will automatically dim the light if internal temperatures reaches 150F (65C) degrees. Immediately turn off light if any parts of the light become hot to the touch.
