The Klarus G20 features a CREE XHP70 N4 LED with 4 output levels. This dual switch mini-search light makes it a great choice for throwing in a camping pack in case of emergency situations. With a max output of 3000 lumens, no blind spots, and a wide beam profile, you can't go wrong with the G20.
The emitter is in a shallow OP reflector, the tail switch is an electronic switch which operates the UI similar to the side switch. The UI for either switch is click for on, and then click to cycle through 4 modes. The tail switch always starts on low, the side switch starts at last mode side switch was turned off at. To turn off is press and hold. Double click from on or off gets strobe, double click again for SOS, single click turns back off or to last mode light was on.
The light comes with an 18650 tube adapter, the adapter the light runs about half power vs using a 26650 battery.
Overall it seems like a pretty good light. The size and form factor is great, and the UI just takes a little getting used to. The modes are spaced very well with each having a noticeable jump in output. The beam pattern has a very large hot spot with lots of spill due to the shallow OP reflector.
