Dive Lantern Pygmy 6 (600 lumens)

This compact light is ideal for scuba divers and free divers who want to: 
- Mount on a mask strap
- Mount on a cray loop
- Store in a pocket as a backup

It has two light outputs based on the battery that is used.  When run on the  rechargeable battery it comes with the output is 600 lumens, but run on a standard AA battery it drops down to 200 lumens. 

At 600 lumens it is great mounted to a mask strap for looking under ledges during the day when the divers eyes are exposed based on the large amount of ambient light from the sun.  600 lumens also provides enough light to be used as a backup.   Used on a cray loop sometimes you don't want as much light as that, so having the option to run either the full 600 lumens or switch over to 200 lumens is ideal.   

Mounted on a mask strap it is ideal for free divers who want to keep their hands free and be able to quickly look under ledges while their eyes are exposed to daylight.
