Description

Reveal stunning colors
The Sea Dragon 4500 professional underwater video light delivers 4500 true lumens in a smooth, even 120° wide beam without hotspots. Its unmatched 96 CRI (color rendering index) COB LED array mimics natural sunlight and adds natural brilliance to your videos and stills. The Sea Dragon 4500 is truly a professional’s video light with a Television Lighting Consistency Index (TLCI) value of 97, which makes it one of the best performing underwater lights in terms of capturing true and natural colors.

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
optimal image exposure control. The Auto features can easily be turned off any time underwater.

Why an “Auto” Underwater Light?
Auto lights offer two distinct features over other underwater lights:  The Auto light automatically adjusts brightness to the optimal amount needed to see or shoot pictures/videos.  This will save battery power for longer run time and preserve your eye’s natural low-light vision.  A light sensor on the front face of the light constantly measures the amount of light reflecting back from the object.  The light will dim when aimed at close-up objects and increase brightness [to full brightness] at far away objects.  Auto lights also include manual brightness control if you prefer consistent light output.

The other purpose of the Auto light is to detect when your external flash (strobe) fires and temporarily turns off the photo-video light for one second.  This prevents unwanted shadows and backscatter that may be caused by the photo-video light.  You can enable or disable the Auto Flash detect feature if you want to use the photo-video light in combination with your external flash.

*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.
