Activating the X1 sets in motion a finely engineered sequence of events culminating in a perfect circle of peak brilliance. Switch-to-piston pressure joins the supplied AA alkaline battery to an intelligent power regulator that steps up battery voltage for constant, maximized light emission up to 10 hours.  With its 65' effective range, 1-mile signal visibility and operational range of -40° to +50° C, the X1 is the optimum light machine in its class.  Compact ? The X1 delivers X Series? uncompromising lighting performance, reliability and durability in a sleek design just 3.9" long by .72" diameter that fits easily in pockets, briefcases, toolboxes and more.   Powerful performance ? The X1 projects a uniform circular beam up to 65' and offers up to 1-mile signal visibility. Power regulating circuitry provides maximum, non-dimming brightness for up to 10 hours.   Thorough quality ? The crush-proof, water resistant X1 is designed, engineered and manufactured to provide reliable operation in extreme environments  

Precision Optics - Patent-pending optical system with double-coated glass lens concentrates light into a powerfull beam.  

3-Position twist cap - Half-turns enable constant on, monmentary on and constant off.  

Piston power - Piston with reverse polarity protection prevents accidental electronics damage and ensures reliable energy delivery to the LED.
