When you acquire the Klarus g20 light, you will have access to 4 light modes and two special modes. The light modes include low, medium, high, turbo, SOS, and strobe. The low mode runs for 150 hours, medium mode runs for 19 hours, high mode runs for 4.5 hours, and turbo mode runs for 0.75 hours. The strobe mode is normally used when in danger and if you want to disorient an assailant. On the other hand, the SOS mode is for use in emergency situations, like when you are lost and need help.

As a result, if you drop it accidentally, it will still perform very well. In addition, it is corrosion and dust resistant.

  1. Fenix lights from Fenix store are far better than any other brands. I’ve been using Fenix for years and their products are indeed well built and portable.
