I picked up two of these Aquatec mini-lights in my last order from Bryan. I am really impressed with these things. I am in that ever continuing quest to make my gear smaller, lighter, and more minimal. The lights either clip onto your mask strap, or have a lanyard for use like a regular underwater light. I clipped one on my mask and carried one. By the end of the dive I stuck the handheld one in my pocket, and was just using the mask strap one. It is absolutely weightless underwater. It literally feels like it isn't there. It is also cool that the beam naturally cowitnesses with where you are looking due to its mounting. You can also turn it on or off with one hand because the bracket and flashlight are keyed together. Even my fancy cave diving buddy with his high falooting cave diving light thought they were bright for how small they are, and he carries a small sun on his goodman handle. Here's some shots from Paradise Springs in Ocala, which is a wonderful place to dive as well:
The light comes with a battery, a lanyard, and the clip
Here the light is on my Aqualung Micromask. The mask sucks, and leaks, but it is the smallest and lightest mask I own, so I figured if the light would be too heavy or pull, then it would be on this mask.
These lights are going to replace my Princeton Tec 40 lights for everyday use. My Tec 40 lights are 28 lumens, weigh 181 grams, and use 4 AA batteries with a 5 hour burn. These Aquatec lights are roughly 10 lumens, weigh 39 grams, use a single AAA battery, and burn for 3 hours. For open water diving these things are awesome. They even did pretty well in Paradise Springs, which is pretty dark being a cavern with a small opening and all.
My buddy shot some underwater video with a Gopro, which I will share when he gives it to me.
Bottom lines:
-Minilights are bueno.
-Aqualung Micromask is no bueno.
