This is a fine handheld rechargeable flashlight. It charges via the included USB cable. It has 5 modes: bright, medium, low, strobe, and flash. The lighted switch is located on the side of the flashlight, unlike many that have the switch on the endcap. The switch lights up green for normal, red when battery is below 20 percent.
This is a bright light. It can zoom in and out by sliding the lens holder. It is made of metal and has rubber seal rings to make it very water-resistant, though not designed as a diving light.
It is very nice and will get a lot of use around our home and in the vehicles.
Note: We tried it using the 18650 battery (which we have many) and it works fine, though you should get some kind of plastic tube so the smaller battery doesn't rattle around inside the light. The 26650 battery will charge either inside the light or by using our charger (see my last picture).
