The Nitecore Tiny Monster TM11 really is a little beast of a flashlight. About the size of a short soda can, it uses 4 18650 or 8 CR123 batteries to power three CREE XM-L LEDs to a maximum of 2000 lumens on high. The switch is a two stage switch similar to what you see on many modern digital cameras, allowing for quick access to the lights many modes. There is even a red LED indicator around the switch that serves several functions.
Please note that this is the neutral white tint model. The cool white version is also available. The specs below are for the cool white version. The neutral white version will have about 15% lower lumens, but better color rendering.
