Go Pro Light Tray for distant shots / schools of fish?

[stephpase]

Hello I'm a photography noob but want to just take the best photos and videos possible for my memories and personal instagram. That said I just upgraded to gopro 13 and I'm thinking about buying a light tray.

Specifically I wanted to buy this to improve my videos for the hammerhead school migration in Yonaguni in Japan. Is it worth it? Like i know the sharks may be a little far so I was hoping it would help? Or is the light just gonna have no effect?

The one I was looking at is 10000 Lumen.

Do you think this tray is worth it to improve my videos here and then in Malapascua for the threshers? and just like general videos of me scuba diving through caves and stuff haha.

Or is 5000 lumen sufficient?

Thank you !!

For things as far away as the hammers at Yonaguni your 10K lumen light will have no effect for schooling sharks, same as at Malapascua with the threshers. For caves it will help but think of lights as good for 6-10 feet away at most.
