Despite measuring less than 3", the EC11 Explorer LED Flashlight from Nitecore delivers up to 900 lumens. With a white CREE XM-L2 (UL) LED as the primary emitter, this light has five brightness settings ranging from 1 lumen up to 900 when an RCR123 battery is installed. Enhancing the versatility of this unit, there are 3 different emergency strobe patterns. A dual switch interface allows you to easily toggle between brightness settings, red light, and strobe modes. You can also directly select turbo and minimum modes from the off position so you don't have to cycle through modes to get the desired output.
