Best Practice Video Light Space Distance in Lights, Strobes, and Lighting Technique Posted June 20, 2019 Hi All. Just starting to get into UW videography and curious-- what rules are there on the suggested spacing of video lights? I'm rocking 2x Sola 9600 flood lights w/ Nauticam housing and RX100IV, and looking at just doing a V configuration with an arm on each side (no "M"). Not sure how long I should get the arms. On a side note: Also curious as to the possibility of using Flex arms instead, and the max weight they can handle. Each light weighs about 1 lb on land. Whole rig weighs 1.2 lbs in fresh water without any arms (weighed in my tub). I couldn't find any information anywhere online as to a table of lumens vs light spacing distance, or a max weight for flex arms. So I think this could be helpful for anybody else trying to get into this hobby. Thanks!
