LED light panel

Lighting equipment for underwater photography. It illuminates every corner even at a wide angle. Dimming by PWM is possible, and it can be installed in ROVs. Compatible with BlueROV2 is also possible.
Depth: ~ 6,000m
Brightness: 5,000 lumens
Power supply voltage: 9V to 20V
Power consumption: Up to 40W
Dimension: 105mm x 93mm x 31mm (excluding protrusions)

 

Example of use

Arduino sample Sketch

 

//
// Check for LED light panel
//
// PWM output from pin 9
// Serial input 0-9 -> 0%-90% (100% none)
//
