In Topic: Gopro - recommended video light arm length?

Galapagos has more surge than currents at Darwin. For still images makes sure you have at least two 8" arm segments or longer and two strong strobes.

I always use two lights. Using only one for video is only possible in gin clear water. Even for macro I use two one as main and the other one as fill light. Galapagos is a challenging destination for photos really no need for a fisheye as there is no coral and no macro either. For your Olympus you need a 7-14 or 9-18 and two good twin strobes. For video the FIT are ok but other than barracudas and the occasional turtle or group of snappers you won't find much use out of them

I shot with my Sony rx100 I had two sola 1200 and I put them on very rarely. You can try lights as you wish but you will most likely end up with just one part of the frame lit up. Better use a filter and forget about it. Some fish do perform well with lights though such as barracudas you can check on my channel the shot on the red sand those are with lights. But for the Sharks lights do nothing. If you are lucky to see a whale shark you wouldn't be able to cover it anyway

For Galapagos light are non that useful. Sharks usually stay at 4 - 5 feet the only subjects that come a bit closer are turtles. Also surf is quite bad and it's better to have a simple set up. I used a tray with two float arms connected as a triangle on top by a single clamp. Invest in a good filter. Considering that depths are around 18-25 for most a magic filter would be ideal. If you dive Isabella the water is really green consider a magenta filter too. In short don't waste time with lights would be my advice

A studio scene is set at 1000 Liz however an overcast day is also sets at 1000 lux. Your mangrove lights at half meter give 5000 lux each so you will possibly see something. In a bright day on a sandy bottom probably absolutely nothing as the environment is already brighter than the light. That's why filters exist. If you are in a cave or very deep the light will indeed be useful. The key is to find lenses that perform well around f/4 and shoot at slow shutter such as 1/50 so that you don't have to bump the ISO too high. But no artificial light can beat the sun I guess and also fish don't like it so only good for wrecks
