Hi @nfored,
I don’t have any relevant footage, but there are a couple of threads on extra lighting that might be worth taking a look at:
- More light for dark waters/very low-light environments
- What are option to add more lighting to existing 4 lights?
I would note that the Lumens originally had a linear brightness curve, but we changed to an exponential one, because we found that it was generally more important to have fine control over the lights in their low levels than it was to have extra light - especially in situations where particulates in the water are causing lots of back-scatter.
Just as an FYI, ArduSub currently only has built in support for two lighting channels, so you might need to get creative if you need more than that (e.g. one channel might need to be configured as a camera pan gimbal or something).
