Although it is nice to have options for charging this flashlight, I have found that I tend to just use my car charger as it’s easier than messing around with cables and adapters while I’m driving around town trying not to get lost!

Performance and Output of SD05 Scuba Light

The Underwater Sofirn SD05 Dive torch performs well in a variety of scenarios. The output is good, with a smooth and consistent beam. The light is not too wide or narrow, and it’s comfortable to use in most situations.

The beam isn’t too hot or cold, meaning you won’t get burned if you accidentally shine the flashlight on yourself for too long (but if you do happen to shine it on yourself for too long, don’t touch/rub your eyes until they stop watering).

Finally, the output of this underwater torch is neither dim nor bright; instead, it sits comfortably between these two extremes so as not to distract from what we’re supposed to be doing: diving!
