Shark Polaris dive lamp

Shark's Polaris is a really powerful but small backup light for diving and the most excellent Additional work light for underwater filming, for example.
The very small size has been given a proper boost, Polaris emits about 600 lumens when using the included SAFT 14500 Li-Ion battery.
The burning time is up to more than 10 hours with the same battery.
If for some reason you don't have a Li-Ion battery at hand, a traditional AA battery can also be used as a power source, which you can easily get from a local store. However, AA batteries have less light output, such 150 lumens.
Light output 600 lumens (with the included SAFT 14500 Li-Ion battery)
Battery life 10 h (with the included SAFT 14500 Li-Ion battery)
Light output 150 lumens (with standard AA battery)
