One of the biggest challenges to underwater photography is the lack of natural light. Water absorbs light quickly, especially at depths of more than a few meters, making it difficult to capture clear and detailed images. A fill light on an underwater camera can solve this problem by providing the necessary illumination.
In contrast to conventional plug-and-play underwater fill lights, Barlus fill lights can be remotely controlled just like underwater cameras. There is no need for on-site control switches. This provides great convenience and flexibility for the user.
Currently, there are 3 forms of fill light on the Barlus:

1. Built-in fill light.
Generally built-in infrared + white light. Each 1000 lumens.
2.External fill light.
Optional external single light/external double light. The cable of the light is integrated into the internal camera. The camera and light can be controlled by one cable.
Optional:
External normal fill light (2000 lumens each)
External super fill light (6000 lumens each)
3. separate fill light.
Separate fill light needs to be controlled by a different software than the camera.
Dazzle light (2000 lumens): different light colors can be switched
Ordinary fill light (2000 lumens): infrared light + white light two modes. 2000 lumens each.
Advanced fill light (6000 lumens): white light.
Super fill light (12000 lumens): white light
Operability:
Supports manual/automatic/timed control of lights. Ten levels of brightness can be adjusted.
Manual mode: control camera mode switching, light brightness, switching light on/off, etc. within the software/webpage/NVR.
Automatic mode: camera tail with photosensitive sensing. It will automatically turn on the fill light when sensing the environment with low light.
Timer mode: You can set the timer to turn on the light. For example, it can be set to turn on the infrared light from 7:00 pm to 6:00 am the next day.
