Light Output is the total rate of transmission of light energy ( luminous �ux ). �is light output is expressed in units of Lumens. �e higher the number, the brighter the light.

Run Time With fresh ba�eries installed, it is the elapsed time ( in hours ) from start up until the light falls o� to 10% of its initial output.

Beam Distance is the number of meters from the �ashlight to where the projected beam reaches 0.25 lux; or approximately the amount of light from a full moon on a clear night, out in the open.

Peak Beam Intensity is the maximum luminous intensity along the center of the light beam. �e value is expressed in units of Candela (the international standard) and it does not vary with distance.

Water Resistance— IPX4 —�is standard has established that water splashed upon the �ashlight from any direction will have no e�ect on the performance of the �ashlight. However, it is neither a waterproof nor immersible standard. �ey each have their own measures and icons.

Impact Resistance is the degree to which a �ashlight will resist damage when dropped, as measured in meters, on to a solid surface. �ere could be some cosmetic damage but no loss of function.

Why Standards ? Until 2009 there were no common benchmarks for handheld portable �ashlights and spotlights. Each manufacturer explained product performance with their unique set of criteria. �e consumer was unable to compare products as “apples to apples”. �e �ashlight industry recognized this and created, through a voluntary consensus development process, a widely accepted set of standards.
