When the power on key is pressed, 250 Lumens light output is illuminated in the space range 40 m. Pressing the button turns on the 120 Lumens cob LED Light emitting diode, which illumines brightly in your environment or work space. The third pushbutton switches between light and red cob lights to maintain a night vision, perfect for hunting and fishing at night.

Powered by a three (attached) AAA battery, the multifunctional head spotlight will give hours of comfortable hands-free illumination.
