@Wurkkos Diving Light Not really sure how all this works, but I dive in darkwater environments pretty regularly (planning to get 20-40 dives in the next three months) and have a decent number of friends/dive buddies who do the same. Between the lot of us, we could definitely put your lights through their paces. I don't keep a blog, but I studied engineering in college, so I have technical writing training for whatever that's worth. I've got the capacity to take underwater footage of the lights, in action, in several different dark/low vis environments, so if any of that seems suitable and y'all're still looking for testers, let me know. If interested, I could also contact a fellow I know that runs dive charters under similar conditions, and see if he'd be interested as well.
