The Nitecore EA81 Caveman is powered by eight AA alkaline/NiMH batteries and boasts an impressive maximum output of 2150 lumens.
The EA81 features a Cree XHP50 Quad-Die LED that is capable of emitting twice the brightness of a XM-L2 LED, yet remains the same size, therefore halving the heat generated.
A micro-textured reflector produces a wide angle of lighting with a smooth beam pattern, that can shine up to 462 metres when in turbo mode.
There is five brightness settings to chose from as well as three special modes of strobe, SOS and location beacon. To prevent accidental activation of the light, the EA81 can be put into lockout mode by pressing and holding both buttons for more than one second, while the light is turned on.
The dual switch has a power button that turns the torch on/off and also provides instant access to ultra-low. The second is a mode button that cycles through the brightness settings with a single click and holding it down enters the special modes.
Pressing the mode switch while the torch is off will indicate the battery power status. A blue LED will blink three times for +50% power, twice when power is below 50% and once when the battery is close to depletion.
