A2 AVIATOR LED
Output & Runtime
Accurately specifying light output (lumens) and
runtime is more complicated for LED flashlights
than it is for tungsten lamp flashlights.
What can be said, in simple terms at this time, is
that the light output of the A2 exceeds the 60
lumen output of comparable SureFire tungsten
lamp flashlights (6P, C2, E2e, etc.), and runtime is
longer than the one hour specified for these
tungsten lamp flashlights.
