The Sea Dragon 3000 Auto (SL678) delivers 3000 lumens over 120° smooth, even beam angle without a hot spot. Two red LEDs emit a 88° wide “stealth mode” beam that won’t scare away nighttime sea creatures and preserves your eye’s natural night vision. Powered by a rechargeable 25Wh lithium ion battery, the light burns for a full hour at 100% power at constant brightness with its new COB LED 120° beam angle. Depth rated to 330ft / 100m.
The Sea Dragon 3000 Auto’s Auto Flash Detect Mode turns the light off for one second when an external flash is detected. This assures a well lit photo and prevents shadows in your images. Select the Auto Bright Mode and the 3000 light’s photocell light sensor will automatically regulate brightness based on proximity to the object in 10-step brightness levels. Includes Flex-Connect Single tray, grip and GoPro® Camera adapter.
Auto Flash Detect Mode & Auto Bright Mode
The Sea Dragon 3000 Auto’s Auto Flash Detect Mode turns the light off for one second when an external flash is detected. This assures a well lit photo and prevents shadows in your images. Auto Flash Detect Mode can also be turned off if this feature is not desired.
The Sea Dragon 3000F (The “F” stands for Flood beam) brightness can be adjusted manually or automatically with its built-in photocell light sensor. The Auto Bright mode automatically adjusts from 300 to 3000 lumens based on proximity to the subject, helping to preserve your eye’s natural night vision and extending battery life. The light can also be manually adjusted to 100%, 50% or 25% brightness.
Red LED “Stealth Mode”
Two integrated 180-lumen red LED’s cast an 88° beam. At night or in caves or shadows, the red LED’s preserve your eyes natural low light function; allowing you to see gauges and your surroundings, at the same time the red LED’s do not frighten fish like skittish reef fishes that disappear from bright underwater LED lights. The red LED’s are powerful enough to assist the camera’s auto focus and will turn off for 1 second when a Strobe/Flash is fired.
The Sea Dragon 3000F is easy to expand with SeaLife’s Flex-Connect system of trays, grips, arms and adapters. The 3000 can be connected to any underwater camera system using standard ¼-20 tripod or GoPro camera mounts. Flex-Connect ball joint, YS and cold shoe mounts are available making the Sea Dragon 3000 compatible with any underwater camera.

*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.
