The SeaLife Sea Dragon 2500F (SL671) lighting unit is a powerful LED photo/video light for diving, designed for underwater photography and videography. It provides 2500 lumens of steady illumination with a 120° beam angle (90° underwater), making it suitable for wide, even lighting coverage without "hot" spots.

The color temperature is 5000K with a CRI of 90 for natural and accurate color rendering. It features three brightness levels: 100%, 50%, and 25%, controlled via a single button with on/off options and a hidden emergency signaling mode.

The light uses a 1 x Vero 18 COB LED array, includes thermal protection that automatically reduces brightness at high internal temperatures, and is waterproof up to 200 feet / 60 meters with dual NBR O-rings and an isolated battery compartment.

Power is supplied by a removable 7.4V 3400mAh 25Wh rechargeable lithium battery, offering approximately 60 minutes of full power operation, 120 minutes at 50%, and 240 minutes at 25%. Charging time is about 170 minutes.

The light head is made from anodized aluminum, fiber-reinforced polycarbonate, and corrosion-resistant metal. It is compatible with SeaLife Flex-Connect accessories and mounts, including trays, handles, flexible arms, ball mounts, cold shoe, 1/4-20 mount, and GoPro adapter. The product belongs to SeaLife’s underwater photo-video series and is modular for use as a standalone light head or in sets.
