Illuminate the beauty of the aquatic world at depths as great as 328' with the compact SeaLife Sea Dragon Mini 900 LED Dive Light. It outputs 225-900 lumens in three levels, running for 2-8 hours per battery charge depending on the brightness selected. The light also features a one-second strobe mode and an SOS function for emergency signaling. SeaLife's Mini 900 ships without batteries, and can be powered by a single 18650 lithium-ion cell or a pair of CR123 lithium cells.

The light offers a 10.5° beam angle underwater and 14° coverage on land. Such a narrow beam works very well when focusing or exploring tight spaces, e.g., the nooks and crannies in a coral reef or cave. Additionally, the built-in release valve on the Sea Dragon relieves the buildup of internal pressure in the light. As a bonus, the Mini 900 includes a convenient wrist lanyard with a clip for your buoyancy control device (BCD).

Light Performance

CREE XM-L2 T6 LED.
Three outputs: 900 lumens at 100% power, 450 lumens at 50%, and 225 lumens at 25%.
One-second strobe and emergency SOS modes, both of which operate at full power.
Run time: 2 h at 100%, 4 h at 50%, and 8 h at 25% with a single 3400mAh 18650 lithium-ion battery.
Ships without required battery. Can be powered by the 18650 cell or by 2 CR123s, which will provide half the run time of the 18650.
Tight beam angle of 10.5° underwater, or 14° on land, is helpful when focusing or exploring nooks and crannies in coral reefs and caves.

Switching System

Push-button on light head for turning the power on/off and cycling through output modes.

SeaLife Mini 900 Reviews

Great light!

I purchased this light as a backup for a Keys trip. Used it on a daylight wreck dive and it had decent penetration. The light is easy to pocket and includes a lanyard & clip for security. I did not use it long enough to test it's charge duration. It does not ship with a battery and the battery must be removed to charge.

Bright, high quality, solid light

After reading many glowing reviews online from users and industry testers, I chose this light. The build quality is very solid and the battery indicator feature is a nice touch. Looking forward to having this light part of my standard dive kit.

question

what type of battery does the sea dragon camera strobe take and what voltage?

Asked by: Anonymous

The 1500 Lumen light uses a Lithium Ion 7.4V, 3400 mAh, 25Wh which is included with the light. Also please note this is a light only and not a strobe.
