Product Information
The Keldan Video 4X (LUNA 4X) is a self-contained underwater LED video light rated at 6000 lumens, designed for divers who shoot video or photo and want a compact light that mounts directly onto standard arm systems without a separate battery canister.
Who it is for
This light suits underwater photographers and videographers who want a small, self-contained unit rather than a light with a separate battery canister. The compact design and light weight make it easy to add to an existing camera rig. Thanks to its overtemperature protection, the light can also be used outside the water, and the Li-Ion pack performs better in cold water than NiMH.
