LED Light system

Hi,

I am looking for LED’s for the ROV, and was wondering if anybody has any suggestions for lights of 700 lumens or more.

I found these lights here:

But I was wondering if there are other options and cheaper options too.

I am using the pixhawk and a raspberry pi via ethernet cable and would like also to have control to turn on/off the lights, I would like to control them via qgroundcontrol (any tips on how to connect them would be also appreciated. I would like to have lights for navigation,but then turning more lights for filming something particular, )

Any help is appreciated.

Thanks,
