Flashlight Lumen Tests by category...
These tests were paid for by CIS Inc. CIS is affiliated with the Arc Flashlight brand.
All flashlights vary in quality from unit to unit, even within the same model type. The test results presented here are for the particular units tested only and should not be assumed to represent all lights from that manufacturer.
No single measurement can accurately sum up the value of a particular flashlight. Prospective buyers of flashlights should not rely on these lumen figures as the only gauge of value. Remember that units can and do vary in output, even among the same model and production lot.
Some units had technical problems or produced less than the manufacturer's minimum advertised value. In those cases, the values were posted until the manufacturer identified the unit as defective.
