The Sea Dragon 3000 Auto 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.
