I purchased the Fenix CL09 Lantern with no real use for a personal lantern but found it to be very versatile and a tool that I use almost daily.
Just over 3 inches long and less than 1 inch in diameter the CL09 fits easily in a pocket. The key ring clip and magnetic base gives you plenty of options for hanging the light.
What’s most impressive is the amount of light the CL09 produces. A simple twist will cycle through the settings of 1-30-80-200 lumens. The additional settings of solid/blinking red or green are also a nice feature and can be useful in a variety of situations.
Paired with a Fenix ARB-L16-700U rechargeable battery run times are good. A CR123A battery can also be used which considerable increase run times.
The Fenix CL09 Lantern’s biggest selling point is it’s versatility. From hanging on a backpack, or lanyard to using the magnetic base for working under the car hood I have found it to be one of my “go to” lights.
