So I reached out to my friend at Illumn. I brought my Chronos 1.4 over to his shop and we tested an Imalent DX80. It outs out 30k lumens on turbo. I tried some really high FPS and reduced shutter speed and did not notice any flicker.
I bought it and tested it when I got home. I was able to film a .22lr bullet traveling approximately 710 fps. I reduced the shutter speed to 40% thinking I would play it back at 20fps. It is kind of dark but you can see the bullet. I took a couple more videos with faster shutter speed and the bullet is rather blurry. Will be testing this some more. The light can operate at full brightness for 3 minutes. I turn it on right before I hit the remote trigger and as soon as I stop the recording I turn off the light. At a few seconds of use per capture think I can use this light for a while before recharging.
