If you turn it down, there is no light on what you are looking. If up, it will bother other divers. So I do not see the interest of the thing.
It's enough for reading gauges, writing notes and such when angled down, which is its intended purpose. I have a bigger primary light for signaling and looking at things further away. It's just that if I do something that requires both hands then I may need to drape the primary or clip it off and consequently not have enough light or not have it where I want it.
