The Sea Dragon 4500 professional underwater video light (Item SL675) is a high power true lumen professional underwater imaging light that not only gives you brightness but also adds color and warmth, all with a smooth, even 120° wide beam that runs for a full hour at the highest power setting. The light offers 4 manual power settings, plus an automatic brightness setting. The Sea Dragon 4500’s COB LED delivers a whopping 96 CRI and a TLCI value of 97.
Auto Brightness & Flash Detect Mode
Brightness can be adjusted manually or automatically with its built-in photocell light sensor. The Auto Brightness mode automatically adjusts from 450 to 4500 lumens to preserve your eye’s natural night vision while extending battery life. Aim the light at your dive computer or other close-up objects and the light will dim automatically. Aim the light at far away objects for maximum brightness. When a nearby flash fires, the light detects the strobe and will turn off for 1 second for optimalimage exposure control. The Auto features can easily be turned off any time underwater.

*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.
